MacBook Pro Model A1707 Intel i7 2.6GHz, 15 Inch, 2016, 16GB RAM  & Intel HD 530 graphics boot but cannot connect to any network (only wireless is an option) and so "crashes" with "a critical update must be installed but cannot connect to network" so all I get it the option to try again or shutdown. So I have a few questions please
1. Is there an option to connect to a cabled network (I do not see any RJ45 connectors on this laptop)
2. I believe the SSD on this laptop is on-board so is there a way to get any user data off this drive if it won't boot in IOS
3. Any other suggestions to get it working again without risking overwriting existing user data.
Thank you.

Using MacBook Pro (late 2011) 2.4GHi7 w 16GB mem 750GB HD partitioned 430GB Mac (42GB avail)/ 231GB Win (31GB avail) Journaled HFS+;
  running High Sierra v10.13.2 w Parallels Desktop 14 for Mac Pro v14.0.1
  Using 2 Airport Time Capsules 4th Gen v7.6.9, 3TB ea formatted AFP (the one being used for backup through Time Machine reports 923GB free through Disk InventoryX app)
  Time Capsules run under Airport Extreme 5th Gen v7.6.9.

Backups through Time Machine > Time Capsule are taking 6+ days (not sure of exact time; I'm having to cancel them).

Ran a few tests (under only MacOS; Windows not booted; Parallels not running); Wi-Fi turned off; Time Capsule connected to MBP via ethernet; running no other apps at time:

Test 1:  dragged 1.0 GB app file from MBP HD to Time Capsule to check write rate  RESULT:  Took over 25 minutes (approx 0.7 MB/s)
Test 2:  ran LAN_Speed Test to Time Capsule with 100MB packet size RESULT:  1.4 Mbps writing to TC, 1.7 Mbps reading from TC

Given the specs on the MBP and TC (1Gps ethernet port) the data transfer rates are excessively slow.

What can I do to fix this?  I can't leave my MBP tethered via ethernet to the Time Capsule for over a week to do a backup (need to take it to work daily).
i can only login to my macbook on safe mode only not when how i does log in normally. i removed the mac from the domain and re-add and its still not working.

I would like to find a way where I can screen share from MacBook to 22x iMacs.
We are running a medical imaging course and it would be beneficial for the delegates to see the slides and content that is being shown by the presenter on a MacBook on the podium up close on the iMacs which each delegate will have in front of them. They will be using software on them later in the day.

I know I could use the native OSX screen sharing software but I wonder if it has limitations when trying to share to 22x iMacs simultaneously?

I presume to maintain performance that an ethernet/switch setup is best rather than attempting a Wi-Fi router.

Any advice would be much appreciated.
What is the process to connect an iPhone X to a remote Windows network using the Always On VPN?
I have had a few people tell me that when trying to visit a site using safari on their iPhones, they get an error that says:

Safari cannot open the page because the server cannot be found.

I asked other people to test on their iPhones and they said it works fine. After asking Google about this it seems that the answer is always something to do with the phone itself. But, it is not realistic to ask everyone with an iPhone to check this setting, and check that setting in order to try use the website.

Does anyone have any suggestions regarding this?

What's the best way to update Mac mini "Core 2 Duo" 2.4 (Mid-2010) from 10.6.8 to either El Capitan or Sierra or at least something newer than 10.6.8. We do not mind doing fresh install. We have other El Capitan Mac which we could use to create an installation image. Can we just install El Capitan and will it automatically activate and not ask for licence serial number? Will drivers still be available?

Mac OSX question

I have a large library of digital media. Most of it is kept "offline" but the library software I use (Plex) uses media files to build the library and so I need to use placeholder files.

Using 30 second "this file is archived" videos I can easily catalog offline movies in Plex. I "rsync" the directory structure without files and then "do cp" a placeholder into each movie directory and rename using the parent folder name.

For TV shows this isn't practical as there can be hundreds of episodes per show. I would like to know if there is a way to duplicate the folder/file structure of a tv show, with many episodes under a single folder, using the same placeholder file.

To reiterate, the ultimate goal is to take a placeholder file eg. "placeholder720p.mkv" and use this file to recreate the source directory with the same filenames. So in the end I will have a folder that looks identical to the source, but consists of this placeholder file duplicated over and over. Also, there are non-alphanumeric characters and spaces in the filenames to be duplicated.

Hello I have a Macintosh MacBook with latest Sierra OS and I configured the basic to acces it via VNC. It works, the problem is that the computer doesn’t look the screen when you are using VNC. How can be locked the screen while you are using via remote the Macintosh via VNC?
I really know very little about Macs.

A friend sent me this about his macBook laptop

I was updating my hard drive with my external hard drive this morning and the computer froze midway through. I turned the computer off and unplugged the external hard drive which may have been my first mistake. The entire hard drive seems to be deleted and I have no operating system. The computer starts up and goes to a list of OSX reinstallation options. At this point I don’t want screw anything else up. I last backed up in mid April so I won’t lose that much considering I send most files out by email.  Can you help get me going?

Anyone know where to start with this? He was using time machine - is that an  image of the hard drive / we restore the image and we're done?  Or is it just backup of certain files / folders? We'd have to install the OS, apps, configuration, .etc?  HGe talked of removing the external hard drive... not sure if he corrupted that too?

Would anyone care to share some advice where to start to get that machine going again?

The machine is only a couple years old.

Somehow, I have a 'mac os and install disk 1' for 10.5.4.  taht's copyright date of 2008.  (NOT from his machine, just a disk I have on my shelf.

And I have a bunch of USB disks if there's a place / need to download the OS.

But I have no clue where to start.

How can certain usernames be hidden from the Mac OS X logon screen window when the login window is displayed as a list of users?

We want to keep the list of users view (and not switch to the "Name and password" option and want to simply be able to hide certain usernames from appearing in this list.

How can this be done?

This needs to be done within a macOS High Sierra version 10.13.4 OS.
How can I script:

Install all PKG in /foldername

Maybe write log somewhere too....

I have a client running Windows Server 2016 Standard. We're mostly PCs but have been slowly adding some Macs (currently have 5). Two of the Mac users are Graphic Designers that often work with large files (10 - 15GB+) and Folders (20 - 40 GB). They work wired (not wireless). They also always transfer the files they need to work on from the Server to their Mac, then move/copy them back when done.

They often have problems with slow file move/copy operations and also experience occasional data corruption and files that 'seem' to copy OK but then magically 'disappear' from the Server folder.

I've read that there are problems between Macs and Windows Server when communicating via the SMB protocol. One solution that seems to be mentioned often is Files Connect by Acronis.

Another option we are considering is getting a dedicated Mac to act as a 'File Server', so the Art people can stay completely in a Mac 'world'.

Looking for anyone who has experienced this first hand and how they solved it. I'm not a Mac expert at all, so any advice is greatly appreciated!!
What are the best software programs for performing file comparisons between 2 different folder locations within a Mac OS X computer?

I need to find out which files and folders exist in one location that don't exist in the other location and if there are any differences between the files within the two folder locations.
I need to find out how often a user has been rebooting or shutting down her Mac laptop.

How can I query the Mac logs to determine the dates and times when a Mac OS X computer has been rebooted or shut down?
How can I determine the last time that a Mac OS X computer was rebooted or shut down?
On a Mac OS X computer how can I add a Mac folder location to the Favorites list within Finder?

I would like to add the "My Drive" folder to this Favorites list (see the screenshot). How can this be done?

PArdon the dumb question.  Not really an Apple Person. I have to install an IMAC w/ an Airport Time Capsule at a client's location tomorrow. They have an existing wireless network but, I'm not sure if it is Apple or not. How do you configure the Airport to use the existing wireless network?  Of note. the location is very large and the Time Capsule won't be near the Modem or router.
What are the shortcut keys or method that can be used on Mac OS X  High Sierra v. 10.13.3 computer to switch from displaying the standard Mac login screen (which displays the usernames & their icons as a list of users to logging on using a User Name and password (so a user can login with an Active Directory account)?

This is something that needs to be done before logging onto the Mac.

The option to display the login windows as: Name and password (instead of list of users) has already been selected (see the screenshot).

For whatever reason when this computer powers up it displays the logins as the list of users. These users are local administrator accounts that only IT should have access to; we don't want the users using or accessing local accounts. The users should only login using their Active Directory usernames and passwords.

So what are the shortcut keys or method that can be used on Mac OS X  High Sierra v. 10.13.3 computer to switch from displaying the standard Mac login screen (which displays the usernames & their icons as a list of users to logging on using a User Name and password (so a user can login with an Active Directory account)?

Let me know if any further information is needed.

setting up AirPort Time Capsule to only work as backup disk (and not as wifi router)

I want to use my Apple Time Capsule just as a network attached backup drive and not a router.

This what I have done:

(I got the following instructions off of apple.stackexchange.com)

To prevent the Time Capsule from acting as a WiFi access point or router, and use it only as a backup disk, just open the AirPort Utility app on a Mac (Applications -> Utilities -> AirPort Utility) and do the following:

1. Select your Time Capsule and hit Edit.
2. Go to the tab labeled Wireless
3. From the Network Mode pop-up menu, choose Off.
4. Click Update, and the base station will restart and load the new settings.

-  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  

OK. So I did all that. The AirPort Time Capsule restarted. But now the computer cannot find it when I go in to the AirPort Utility.

See screenshot:
Oh boy. So now what did I do?

I think that the instructions that I got from that website lead me on the wrong path.
A company I am working at has Mac laptops that all have local user logon accounts.

We have added a Server 2016 domain controller and the users will now be signing onto Active Directory to log in to their Macs.

What utilities or methods are available to migrate all current settings and data from these user's local Mac logon accounts into their new Server 2016 domain logon profiles on these Macs?
Currently experiencing an issue with access to mapped drives using SMB protocol with a MacBook Pro running High Sierra, we only see this issue with that machine. The problem effects the user when attempting to move or rename a file in on the share, the MacBook becomes hung up, showing only the spinning pin wheel and needs to be completely restarted in order to allow the user to use the computer. I found the article below attempted recommended changes (no resolution) also opened a ticket with apple support and was directed to open a pay per incident ticket because the technician had no insight other then what I performed on the issue other thanking for directing him to apples article and saying that what he recommends I should attempt.
