Hey all,

I have a wierd one here.. I have a client running 2012 R2 - this runs their file & print sharing, Active Directory and backup software. The IT officer that I deal with has been asking me to help him with an issue, which is the server goes offline and has no connectivity. The server remains on and the OS is in tact but the network card says "no internet" unidentified network.

DHCP is running through the firewall which is (Default Gateway / DHCP). Long story but we will leave that.. This firewall is around 8 years old btw so it could be the culprit and will be providing them with a test unit to see if we can narrow down but I haven't given you the curve ball yet.. wait for it.

Things we have tried;
  • Checked error logs at the time it drops and nothing pops up at the time of the drop out.
  • Testing all cables running from server, Tested OK.
  • Tested connecting to the Firewall LAN port, tested OK.
  • Swapped NICS from NIC4, to NIC3, NIC2 on the server and still no go.
  • Checked all the IP config is ok. (server) / / (gateway) / (DNS)
  • From a client's computer, provided a static IP address. Cannot connect to server or gateway so it does not see the network at all which is odd
  • We have swapped out to a new switch as a test which we will leave there for the time being
  • Checked DNS services, forwarders & entries are correct on the server

In Mac OS Mojave, I'm contending with lengthy delays in applying changes to network interfaces. Sometimes 60 seconds to apply a change to Service Order (i.e. move Ethernet ahead of wifi) or to configure a Static IP address.

The Network Pref window also appears blank when first loaded and takes a full minute to populate. (I have many network configs in my list)

When preparing, testing, and troubleshooting networks (a big part of my job) this is really bogging me down. Never saw this before with any previous release. Always in the past changes are instant with no "apply" delays.

This symptom continues after installing 10.14.2. I've also tried:

- Resetting PRAM
- Resetting SMC
- Reinstalling MacOS using Recovery Mode
- Removing all 3rd party apps that could interfere
- Booting with Shift key down - no performance improvement

My last move is to wipe the machine and recover from backup, discarding the network config option. However since I have so many VPN configurations this is a really big deal.

I'm hoping someone has some other suggestion.
old setup - got a mac with pop3 email account
new setup - got a mac with office365 email account
i am migrating a pop3 account to office365, i successfully moved all emails and contacts. i manually copied all items into office365

but how do i migrate pop3 calender to office365 calender ?
i exported from old pop3 account and imported into office365 email. it created "under my computer" and showing the exported calender . but how do i bring it into office365? so i can see it from web portal ??
hello everyone I have a user that's running Mac OS Mojave the user deleted a folder by accident and then empty the trash can. I am very familiar with NTFS and fat partitions running Drive recovery software to recover things that were deleted in the trash can but I've never had this issue with a Mac any suggestions? also, they were running iCloud backup but because they remove the folder and threw it away it removed it from the iCloud.

I am thinking of taking out the drive and connected it to another mac using my USB to serial cable but I do recall in the past that I used a thunderbolt to USB to connect a hard drive of a non-booting mac to another mac to access the drive, I am wondering would this work instead of removing the drive?
Hi guys,

I got a pop3 email in mac outlook. I want to transfer all emails to a office365 outlook profile in my Mac computer. I recently migrated from pop3 to office365. So doing this transfer to have my old emails in office365.

So in outlook, I got both profiles now. Old pop3 email and office365 Email. I can drag and drop each folder email. But there are many sub folders in inbox, which will
Be difficult to crate all folders in new office365 inbox and then doing drag and drop each folder.

Is there any other way to do it in a better way.
I have a mac book pro that since Thursday, all of a sudden, it disconnects from the LAN.  The wifi works fine.
I replaced the network cable and the 5 port switch that it was plugged into. I have also tried a different computer with the same cable, and
it didn't disconnect with a different computer.   Since a different computer works fine with the same network cable, I'm thinking there's an issue with the MAC.

I don't use MACs much, so suggestions I can try to isolate the issue?

I'm currently using DHCP with windows servers.  I have about another 9 or 10 MACs on the network, and no one else reported any issues just yet.

Thanks. D

Is there a way to setup a specific folder to backup to iCloud instead of the entire Desktop?

I have a bunch of files I want to place in a folder on my desktop, but I don't want it to backup to iCloud.  I have another folder that I like having the files backup to iCloud.  Can this be separated?
US Postal Service exposed data of 60 million users


A broken U.S. Postal Service API exposed more than 60 million users by allowing a researcher to pull millions of rows of data by sending wildcard requests to the server. The resulting security hole has been patched after repeated requests to the USPS.
I have a group of four users experiencing the same problem.  They are all using Macs running High Sierra and Office 365.  Additionally, these macs are connected to a Windows 2012 R2 server for file sharing.  Although the problem happens periodically in other applications the primary issue is when they are using Excel.  

User can open an Excel file from the network share and work on it and save it unless the computer goes to sleep.  If, for whatever reason, the computer is idle with the file open and goes to sleep, the file becomes corrupt somehow and they cannot save it.  I've tried to save it back to the share and to other locations (i.e. desktop) but it does not work.  Basically the file will not save anywhere.  As long as it is open, they can continue to work in the excel document, they just can't save it.  They receive an error similar to the attached image.Excel Error

I'm learning Firebase Functions and have setup my Mac with the CLI. When I initialized Firebase I somehow ended up with the functions project in my home directory instead of where I wanted it usr/Documents/firecast.

I've tried logging out of FB and logging back in the correct directory and re running firebase init. Seems no matter what I do it reverts back to ~usr instead of usr/Documents/firecast.

Any ideas how I can fix this?
Two physical SSD drives and one Time Machine backup

I am about to upgrade my MacBook, which has a single 500 GB SSD, and I need more space ASAP. I bought that drive in 2013.

I would love to get a new, fast 1T SSD, but don't have the cash, and am considering using the CD drive on my MacBook for a second 500 GB SSD.

But how does this work with Time Machine?

I love to be able to plug in an external backup drive and know that when that external drive is unmounted, it contains all the latest files.

What about if I had two physical drives?

How does Time Machine solve this new wrinkle?

1,640 Free (for non-commercial use) Icons in a Single Download

Like custom icons?

Though there are lots of places all over the web to grab Free Windows Icons from, in my experience, the majority of them aren't really free, in that they will let you download maybe 10 or 20 and then require a subscription fee if you want to get more, or be able to download more than one Icon at a time.

I recently found a website that gives you 1,640 Icons in one download.


Just click the Blue download free button and you'll get a ZIP file 68.8MB in size.

Inside that zip file, you'll find 1,640 custom icons that are 100% Free for non-commercial use.

Extract the zip file contents to a temporary folder and you'll have the following folders;

  • 16x16 - All Icons in .png format saved to 16 x 16 pixels in size you can easily manipulate and convert to .ico
  • 24x24 - All Icons in .png format saved to 24 x 24 pixels in size you can easily manipulate and convert to .ico
  • 32x32 - All Icons in .png format saved to 32 x 32 pixels in size you can easily manipulate and convert to .ico
  • 48x48 - All Icons in .png format saved to 48 x 48 pixels in size you can easily manipulate and convert to .ico
  • glyph - All Icons in .png format in various sizes - so that you can easily manipulate and convert to .ico for yourself
  • icns - All Icons in .icns format - these are in MAC format for Macintosh users
Need some help in tracking down an IP conflict that I have.  DHCP servers are Windows 2016 servers (setup in a failover scenario) but I have a MacBook that has had this happen twice in the last month.  He will get a popup saying:

Another device on the network is using your computer's IP address (  

I'm not sure if this IP was for his wired connection or his wireless but only seems to affect his MacBook.  With DHCP servers there shouldn't really ever be IP conflicts (unless someone adds a static IP which I don't think this is the case here - it could be but I doubt it).  In DHCP servers, logs don't show anything...

Anyway at this point to track down what grabbed the .204 IP?
I’ve got a MacBook Pro, running High Sierra 10.13.4 & an HP OfficeJet 4650 All-in-One printer & can’t get them to work together. Using the HP software, I get no devices detected.
If I connect Mac to the printers built in WiFi network, it detects & sets up ok, but of course there goes my internet connection!
We have a very simple network (home router, few PCs and Mac, all running latest respective OSes) and for some reason when we share a Windows folder (for example C:\Network File Share) to the Macs we are able to see the folder inside of it (for example C:\Network File Share\Example) however we can not see the files in the folder.  We actually have to go in and share (example C:\Network File Share\Example) the folder to see the contents (files).  What are we doing wrong with file sharing to be able to see the folders but not the files?
I have a Mac connected to a network but can't get the "other user" account to pop up when u reboot or logout... I see it appear when I turn on the guest account and logout but it disappears after  few seconds ....I also tried manually setting the DNS and that was a no go ... I am able to ping the domain from Terminal. I have all the log in options set correctly but I just can't get that option does not populate to the screen.
I have WinZip Mac Optimizer on my MacBook Pro 2012 under Yosemite (10.10.5). I have been using the product for several years. Regrettably, for some unknown reason, I keep getting an error box "Backup removal unsuccessful - The selected redo point(s) could not be deleted. Please try again." Despite selecting the "OK" box, the error message keeps repeating every few seconds. I have no way of judging how effective this product is. However, I would be grateful for any suggested resolution to this vexing problem. BTW, I cannot upgrade to a more recent Mac OS because I use Boot Camp for my Windows 7 essential applications, which cannot be used in Windows more recent operating systems. Appreciatively, Arbyem

Hello, we have a mixed environment of windows and apple computers.  We have a windows file server that is running windows 7 SP1 with an IIS local website running.  Its an aspx page.

This works just fine on the windows computers.  I can access the http://websitename/ without a problem.

The problem is trying to pull up the site on any of the apple iMacs.  I can't get it to pull up.  

The iMac that I tested on was on OS X Yosemite Version 10.10.5

In any browser (Chrome, Safari) I get an error 'ERR_NAME_NOT_RESOLVED' or 'Safari Can't Find the Server'

They are using airport extreme and ethernet at the same time.  

So far the only thing I tried was changing the service order of the network to ethernet first.

hi Apple folks

i prefer using Xcode for Python programming but i notice it has no native support (or full-featured) for debugging Python using Xcode. or, probably i missed something with Xcode?

basically, how can i have full-featured debug functions for Python code using Xcode?
