Turning on firmware passwords and encryption requires perfect password records and backup habits.
A dying encrypted drive is beyond my recovery skills.
I have dealt with the problems caused by both many times and have yet to deal with malware.
Adware, scareware, phishing, identity theft yes, I have been called to fix these.
But, I deal with individuals and small businesses.

Modern OS from Windows 7 onwards will disable disk cache and you will not have performance gain on using a RAMDisk.

Besides, the wearing from disk read and write will not have a significant impact to your SSD.

https://www.howtogeek.com/256859/dont-waste-time-optimizing-your-ssd-windows-knows-what-its-doing/

I have changed the HDD to SSD for a number of desktop PC for more than 18 months and they are still running to top speed like Day 1.

Before I changed to SSD, I did use RAMDisk to make Windows 7 ran faster by moving all cached and temporary files to the RAMDisk and my experience shows that the article in the link above is correct.

Besides, unless you are staying with 32 bit MS Windows, you will not have spare RAM for RAMDisk and it is better to let the OS to handle memory management.

I found that on my Windows 10 64 bit machine with a 256gb boot SSD (1tb data drive HDD 7200rpm), RAMDisk made a huge difference.  I found the same on my brand new laptop (Lenovo Yoga) with SSD.  I even bought the software.

I was prompted to write this article after the recent World-Wide Ransomware outbreak. For years now, System Administrators around the world have used the excuse of "Waiting a Bit" before applying Security Patch Updates. This type of reasoning to me is flawed and borders on irresponsible behavior!

We could spend the next millennium discussing the differences of the Mac and Windows platforms. The next century will continue to have fanatics on both side of the equation and neither side will win the war. However, that’s not why we are here.

We’re here to discuss reality and the reality is that Macs exist not only in a little corner by themselves, but they are more frequently being used in organizations that are very Windows-centric. This can not only be frustrating for end users, who have problems using their Mac in a Windows environment, but also for system administrators who have to integrate these “foreign” devices into their networks. So let’s take a look at how these two adversarial systems can work together on one network, together in harmony.

One of the major problems is simply integrating the Mac into the network. A lot of system administrators don’t know that the Mac OSX has the ability to join the network. This should be one of your first tasks when you bring your Mac onto a Windows-based network. You can join your company’s Active Directory (AD) server by following these steps:
 

1.

Click on the Apple icon in your task bar and go to System Preferences.

2.

From there, you want to click on the Users and Groups icon.

3.

Once there, you will want to click on Login Options and click the lock at the bottom to allow changes.

4.

You will click on the “Join…” button that has lit up now and you will be able to enter your …

There are other things that, I feel, should be mentioned here.

When removing unwanted or unused programs from your computer, the standard windows uninstaller frequently leaves files and registry entries that should have been removed.  This is also true for some 3rd party uninstallers.  One program that consistently removes everything, and gives you an option for uninstalling in safe, medium and advanced modes is the Revo uninstaller.  It will present a list(s) of left-over items and allow you to select the ones you want to remove.  Even Microsoft Help Desk personnel use this program when remotely working on someones pc.  It begins by using the standard uninstaller (either the software's own or windows) then collects left-over information and presents it to you.  Very user-friendly.  Left-over registry entries are included in items presented to remove.

You can go to the start menu and click or type run and a window will open.  Type in %temp% and click <ok>.  A window will be opened that presents a list of files.  Select all of them and delete them.  Some may be open and so just skip their deletion.

Go to your C:\ drive icon in My Computer or the file explorer and right click on it and run Disk Clean up.  Here, you can clean up system files as well, such as, windows log files, left-over windows update files, and others.

Additionally, just running the defragmentation program does not ensure that all files have been defragmented.  Go to the start menu or search programs and enter cmd and select the program.  A Command prompt window will appear that you may be familiar with if you have ever used the old DOS prompt, which is basically what this is.  Type in defrag ? and <ENTER>.  A list of defrag options will be presented that you can specify when you run the defrag command from this window.  Specify the ones you want and run the program.  NOTE: you may need to run this with administrator privileges.  Do this by right clicking the cmd prompt program and then click run as administrator.

Always remember, your computer may never become faster than it was when you first purchased it and opened the box.  If it was slow to start with, barring pre-installed software, it will usually be this slow to end with and you may need to just go ahead and purchase one with a faster processor etc.  One item that may make a difference here is more RAM.

The following comes from Wikipedia.
 "A myth has arisen that RDC significantly slows local file transfers and should be switched off; a Microsoft TechNet Web page by a Microsoft Directory Services Team member comprehensibly debunks this with detailed timings, additional to the fact that a service which is not invoked by software cannot have any effect, detrimental or otherwise"
 I did not find the TechNet page but would like to see Microsoft's comments on RDC.

I have found the most common causes of slow computers are
1- malware
2 - slow hard disks especially 2.5" drives. They do not report as faulty but the tests take an exceptionally long time to complete. We use Spinrite to test them
3 - as mentioned earlier, all the crap software the manufacturer has auto starting on boot. Ccleaner is great for disabling them.
4 - also mentioned earlier - not enough RAM

Why have a bootable USB Thumbdrive?

While Apple's move to having Mac OS X updates be entirely done through the App Store is very streamlined and convenient in most situations, it presents a challenge if you need to troubleshoot your Mac or have several Macs that you need to manage. In the past, you'd generally use the install discs, but now those don't exist and most Macs don't even have DVD drives anymore.

Which is why having the latest Mac OS X installer and a bootable system on a USB thumbdrive can be an absolutely invaluable tool. Not only does it make it easier to upgrade or install the OS if you've got several Macs to manage (since otherwise, you'd need to have each individual one download the update via the App Store) but you'll also get key tools for diagnosing and fixing a problematic system.

For example, Disk Utility can't do most of its magic on the boot volume, but by booting from the USB drive, it'll be able to do its thing.

Fortunately, the process is pretty easy and thumbdrives are cheap, so there's no reason not to!
 

Getting the Yosemite Installer

1.) Open the Mac App Store and find the Yosemite Installer.

2.) Download it. (Note that this assumes you've already installed Yosemite on this system and the installer was already automatically removed. If not, then your option will be to install Yosemite, but after the download is done, you'll want to skip over to creating the Installer Thumbdrive prior to continuing …

We all know shortcuts makes life so much easier and saves a lot of time in day to day computer work. Here come 10 of the most useful shortcuts in Mac OSX for daily repetitive chores on your mac.

#1: jump between open programs

CMD+Tab jumps to the next program you've opened in your session. CMD+Shift+Tab jumps one program back in the row of programs. You can even use the arrow keys to move back and forth between programs.
Jump between your open apps easily

#2: Close a window or a tab

With CMD+W you can close a window in your browser or in any program which uses multiple windows. Very useful when you have several tabs open and you don't want to click that little X there one by one.

#3: Close a program

Close a program fast by using the shortcut CMD+Q. Instead of clicking the red little bubble in the window of your program the CMD+Q shortcut does the trick without using your mouse.

#4: Open the spotlight

By using CMD+Spacebar the Spotlight will be up and ready. By clicking it again, the spotlight vanishes again. Spotlight is very useful if you want to search files or folders on your mac. Comes in handy so often in my daily work. CMD+Spacebar and there it is.

#5: Selecting text

Actually there are more shortcuts involved in selecting text. In your daily work you may be dealing with a lot of text documents and e-mails. If you want to select all the text press CMD+A. Try it on this article! Handy, right? If you want to cut text out …

Syslogd is a utility that traps and logs messages sent by running processes. It is configured with the syslog.conf file, which consists of lines containing a pair of fields: "the selector field which specifies the types of messages and priorities to which the line applies, and an action field which specifies the action to be taken if a message syslogd receives matches the selection criteria." (from the syslog.conf(5) man page). This is supposed to enable you to, for instance, focus certain logs on messages of high importance from a range of sources, focus other logs on a single function, and so on.

A longstanding fixture to the man page warns that the documented configuration rules do not always work:
Bugs
The effects of multiple selectors are sometimes not intuitive. For example "mail.crit,*.err" will select "mail" facility messages at the level of "err" or higher, not at the level of "crit" or higher.
To be more blunt, multiple selectors do not work correctly. For instance, the OS X server stock syslog.conf file contains the following directive:
*.notice;kern,authpriv,remoteauth,ftp,install.none;mail.crit          /var/log/system.log

That directive should result in the following messages being logged in system.log :

Ransomware-A Revenue Bonanza for Service Providers

Ransomware – malware that gets on your customers’ computers, encrypts their data, and extorts a hefty ransom for the decryption keys – is a surging new threat.  The purpose of this eBook is to educate the reader about ransomware attacks.

The error "There was an error performing the update" occurred on a Mac OS X client workstation running Symantec AntiVirus for Mac - the Enterprise product version, not the consumer-oriented Norton AntiVirus for Mac.

The message itself is not very helpful... In order to see a more helpful error message, you'd need to look at the log file : "/Library/Application Support/Symantec/LiveUpdate/liveupdt.log" where you'll find the more descriptive: verifyCertPath():  objCertJ.buildCertPath failed to get cert path.

When I saw the above error message, it occurred to me right away that communication between the Symantec client and their servers was failing. Perhaps I might need to update a certificate by manually installing it ? The fix is easier, in fact. Update the Symantec LiveUpdate itself, which is a 4.6 MB .dmg file.

See Symantec's article here: http://www.symantec.com/business/support/index?page=content&id=TECH154634

If you are managing your Macs centrally with Apple Remote Desktop (aka "ARD"), you can use "Send Unix command…" to verify the LiveUpdate version on the client workstations using the following:
defaults read /Applications/Symantec\ Solutions/LiveUpdate.app/Contents/Info CFBundleGetInfoString

Open in new window


Using ARD, you can centrally push/distribute the updated LiveUpdate by mounting the .dmg download from Symantec, and using the package installer within. After that, use the below command to get the client workstations to update. I suggest updating everything, rather than just (virus) definitions. All on one line:

The /etc/authorization file in Mac OS X 10.x can be used to control access to the various panes of the System Preferences amongst other things. It’s used by some of us Mac Sys Admin’s to give Standard Users access to System Prefs panes that only admins could otherwise unlock.  It can also be used in the reverse to lock down panes you don’t want users messing with. An example by Apple was all Allowing non-admin users to change the time zone setting - http://support.apple.com/kb/TA23576 Often the panes can’t be controlled to the exact level you may want via MCX (Local or Managed) or defaults write / plists.  Nor do you want to give users admin rights in a large business / university.

With 10.6 and now 10.7 the following Preference Panes are locked by default.  Meaning you need an admin username and password to unlock them: Security & Privacy, Print & Scan, Network, Sharing, Users & Groups, Parental Controls, Date & Time, Software Update, Time Machine and Startup Disk.  As a ‘Standard User’ you can’t unlock these panes.

locked-sysprefs.jpg

In 10.6 we could do the following to the /etc/authorization file, to give a standard user semi-admin access to the Preference Panes.

<key>system.preferences</key>
 <dict>
 <key>allow-root</key>
 <true/>
 <key>class</key>

If you other experts are anything like me you are always looking into and testing out new features. While I was doing some research one day I ran across an app that I installed on my Mac and used as a security system. Mac OS X: SecureHome uses your Mac's built-in microphone to listen to potential intruders and sound an alarm if any noise reaches a user-defined threshold.

If an intruder is heard, the app can sound an alarm to try and scare them off and email an alert to your smartphone. Some of the features of this app are as follows:  Automatic Threshold Detector (ATD): To set a threshold automatically, select the ATD and slam a door at the other end of your home. SecureHome will tailor the default threshold for your home. Alarm sound: Select whether or not you want SecureHome to sound an alarm (in addition to sending out an email) when it detects a sound exceeding the threshold, and choose the duration of the alarm. Reports: SecureHome will document each alarm trigger and corresponding sound level so you can refine the threshold to minimize false alarms. Email on trigger: When SecureHome detects a sound that exceeds the threshold, it will send an email to the account of your choice. This gives you the option of calling the police or disarming the alarm if you accidentally trigger the alarm yourself!

All you have to do to set it up is open the app, set the alarm threshold, and enter your email address if you want to get notified via email. The big downside of the email…

Deploystudio is a system which can be used to deploy OSX clients and servers within the small/medium or large business environments. The system is built ontop of the OSX Server NetBoot system and uses images & workflows as its core assets. Although very powerful, the system isn't the easiest thing to install correctly. Through this guide I hope to provide an overview of the process for a simple & standard install. Comments are welcome, but keep in mind i'm intentionally keeping it simple as it forms a pre-requisite to my future OSX articles.

Start OSX Server manager that is located on the dock towards the bottom of the screen. Ensure that the local server name is listed in the tree view on the left, select it and the server information should be displayed in the main window on the right

Deploystudio is a system which can be used to deploy OSX clients and servers within the small/medium or large business environments. The system is built onto of the OSX Server NetBoot system and uses images & workflows as its core assets. While working at my current employer I was asked to upgrade the organisations OSX platform providing tight windows integration and a more efficient deployment system. After some research I chose deploystudio due to its performance and capability for customisation.

Although feature-rich, deploystudio isn't so intuitive for the novice OSX engineer and it's my aim through this article to provide a quick step-by-step overview of client deployment using deploystudio(DS). Although advanced customisation is outside the scope of this article I do hope to provide reasons for any decision I make and would welcome any comments & experiences.

Pre-requisites

A OSX server installed and configured as suitable for your environment ( a example install here  )

Netboot Installed and enabled - and a suitable image folder prepared ( guide here or here )

Deploystudio Install with default options ( also explained here or here )

Connectivity using SMB

Symptoms

When connecting to Windows Server shares from a Mac you receive an error similar to "Connection failed because the original item could not be found"
Authentication persistently fails to a Windows Server from a Mac with known good credentials
"Server could not be found" errors
You can authenticate to your Windows share but your files are not showing up
You can authenticate to your Windows share and see files but you are unable to transfer files, modify files, transfer large files or all of the above.
You receive -36 errors in conjunction with "Wrong user name or "password"
Your file server is part of a Windows 2008 Cluster and your 10.5 and 10.6 machines are unable to connect to shares. Whereas, your 10.4 clients can connect without an issue.

Domain controllers by default are enabled to “Digitally Sign Communications” always for network clients and servers (prior to a server being promoted to a DC this setting will be disabled. 2008 R2 only enables this for servers). When this is the case a Mac running Tiger (10.4.x) or below will not be able to authenticate to a Windows server. After entering your credentials you’ll receive an error saying something along the lines of “server could not be found,” when clearly it’s there because it asked you to authenticate. All the hassle is actually an easy fix …
