User has other shared calendars viewable in Outlook for Mac so he must have been able to add them at some point.  Also tried the File, Open, Other User's Folder and that is also grayed out.  Mailbox is in O365...

Thanks in advance for the help...
I have a Mac book pro which was running on old version - 10.9.7 with Windows running on boot camp. I am not familar with MAC side and always used windows only on this mac.

Recently, due to some issues on my iphone, had to take my phone and mac to apple store which ended up doing a big update on my mac i believe to version 10.13.7 and helped with my iphone restoral which was successfull.

I came home and logged in to windows and noticed that one of the partition on my windows side disappeared i.e Z drive. I originally had C drive and Z drive. I am not really concerned about the data on my Z drive as i do have it backed up but I am curious what happened to it ?  I checked disk management on windows and there is no partition.

I logged into mac side and could only see two drives BootCamp drive ( c drive of windows ) and the Mcintosh HD drive. It is as if my Z drive partition completely disappeared.

Two questions at this point:

1. Any idea what could have happened to my Z drive ? How can this just disappear ?  Is there something simple I am missing.

2.  Inorder to get Z drive back, I started process of Partitioning my Macintosh drive ( Currently 400 GB into 150 GB for Macintosh drive and 250 for new created Z drive )
     Its currently running the process and applying changes to the harddrive.

It is now stuck on this checking object map for about 3 hours now and I am concerned is it even doing anything ?  Mouse cursor is …
I am unable to connect my Samsung Galaxy CORE LTE cellphone, using Kies vesion 3, to my MacBookPro 2012 (OS 10.5.5 Yosemite). The "connect" box shows "working" continuously, with no success in connecting (to be able to transfer photos from my cellphone to my MacBook Pro. I have downloaded the most recent version of Kies, and installed it (but without uninstalling the previously installed version). Any suggestions to resolve this issue? Appreciatively, RBM

Indeed there is no such file, whereas there is a file /Users/barrygbrunning/eclipse/java-oxygen/Eclipse.app/Contents/Info.plist.  At the install log errors referenced path /Users/barrygbrunning/eclipse/java-oxygen/Eclipse.app/Contents/Eclipse/ are located folders: configuration, droppins, features, jre, plugins, readme and the eclipse.ini file, but no info.plist.
The implied "Deferring..." action seems to have not happened.  Any suggestions as to what I might do to recover the situation?  What should have happened to an info.plist somewhere? How might I get the CFB perspective to manifest in Eclipse?

Any help will be greatly appreciated.  Thank you.

Hello all,

I am looking for a free remote desktop solution for Ubuntu.

My company recently switched from Windows to Ubuntu for desktop computers, but our developers need to remotely connect (with access to the Ubuntu GUI) from their Macbooks.

For a few weeks, we have been experimenting with NoMachine; a wonderful, versatile, and secure application which I fully endorse. Unfortunately, their per-year licensing fees might be cost prohibitive (BTW, it is free for non-commercial use). As part of my due-diligence, I must find a free alternative (like we had when our desktops were on Windows 10).

Our criteria:
- Must be free to use without restrictions (or a significantly lower cost than NoMachine's $44 per user per year)
- Must pass our internal security testing. For one, it can't rely on external servers like Teamviewer.
- Must allow remote access to the Ubuntu desktop GUI from MacOS.
- Must be relatively easy to script and preset by admins for distribution in a standard Ubuntu image.

I've looked at a few options, such as:
  • - xrdp (potential problem: I can't find a recent binary and it seems like a dead project)
  • - VNC (potential problems: there are so many variations. Finding an acceptably secure one is still in the works. Might not allow for a remote session that locks/blanks Ubuntu's (host) physical monitor(s). Might not support dual monitors from host. One example that I'm investigating is x11vnc with RealVNC viewer on the Mac side.
How would one go about upgrading MacOS devices to the latest OS (High Sierra at the time of this post) through terminal commands only?  For example, a device running El Capitan needs to be upgraded to High Sierra.  I am looking to run this command across multiple MacOS devices, and for a command or script that could run on any MacOS device.
how to reinstall mac os x  tiger 10.4 imac a1208 .. I have downloaded  macosx 9  virtual box  but I'm not sure how to open configure and where to start
I am moving to my MacBook Pro; HighSierra 10.13.5 from my old PC that finally died. The Mac has a new install of o365, Outlook v2016. I set up my email (cox.net/imap); and it works great. The problem is importing my .PST from my current Windows PC; Outlook 2013. The .PST is approx 2gb. The import works fine; no errors, but when I restart and look in "On My Computer", there is nothing there; no inbox; folders; nothing. It DOES import Tasks (Categories, etc). Anybody have any ideas? Thanks in advance.
I understand that Microsoft's Support and Recovery Assistant (SaRA) is able to troubleshoot Outlook for MAC versions 2016 and 2011.

Is it possible to install and run SaRA on a MAC client? Is there a .dmg available for download?

Thanks in advance for the guidance. I've been unable to find an answer.
We have a mac in the shop that when you tunr it on you get the mac chime, then the apple logo, and then a progress bar. The progress bar move about halfway and then the screen goes white. We have tried online recovery, reset NVRAM and SMC, safe mode, and CTRL+R. None of these have gotten us anywhere. Just wanted to reach out and see if anyone had any other ideas. Client is a photographer and has tons of pictures on this mac. Was trying to keep from having to offload the pictures and reinstall.
I have multiple macs logging into an AD domain. This has been the case for 7 years. No problems for 7 years. Suddenly, I am having multiple Macs unable to log back in after their screensaver has kicked in, or their computer has gone to sleep. They are told they have an incorrect password. The only way for the user to log back in is to force the Mac to shut down, wait a few minutes, then boot back up. Once done they are able to login. Most users this has happened to were able to do this once or twice and the problem disappeared. One user has not been so lucky. I have been working on her system for 2 days now with no luck.

One common solution to the problem is to turn off the password requirement when waking the computer. However, in a work environment, this is very insecure. I have tried other solutions, including increasing the DSBindTimeout. Now I am at a loss.

I have a mac book with a 500 GB hard drive. 445 GB of its space is labeled "other". how can i find out what that is and eventually clear it out? the OS is sierra.
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?

My internal SSD is APFS with High Sierra 10.13.4 and I have no Time Machine backup. Accidentally deleted important files from trash. Do I stand a chance to recover files trashed? It contains important MP4 and MOV of around 2-3 gigs. Please help.
Computers running OSX (Not sure what version) all of a sudden are having problems resolving DNS.  This is all within the same household.  The family can go to a local coffee shop and experience the same issues while connected to WIFi there when no one else is having the problem.  The latency only seems to be an issue when you're using a web browser.  If you run nslookup from the console or ping, no problems are evident.

  • DNS resolution from the console is instant no matter what.
  • Flushed DNS Cache
  • Reset PRAM
  • Reset SMC
  • Tried different browsers, DNS resolution in all browsers takes 30-60 seconds per domain.

Please advise.
Is there a way of forcing the time to be shown on the menu bar in full screen mode without having to move the cursor/mouse to the top of the screen or pressing any buttons or working in non full screen mode?
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.
Running exchange 2013 & having problems with a Mac client, running Outlook 2011.
I keep getting the message 'The folder cannot be synchronized with the server'. There is an option to empty the cache, but is that on the whole inbox or a folder inside it, as this user has a whole lot of them. There is a warning on the empty cache page, so I am wary to run that, fearing that it may delete emails, folders, etc.
Is there a way to see if it is a specific folder causing the problem?
Don't know if this is related, but the first folder in there has a ' at the start of the name, I'm assuming so it will be a the top of his list of folders.
Could that be part of the problem?
Trying to replicate issue on my mac & after a few attempts, I'll get the message 'Outlook must be closed because an error occurred', which he is not getting.
Mailbox is 7.1 GB, if that matters, either.
No matter how long I press the power button it won’t boot up. It just started this

Hi Peers,

I need your advice and guidance.

I have an excel database called Master-Document that I need to import several hundred excel files in a folder into.

Unfortunately, this needs to be ran on a Mac and I am no expert on using Macs.

Example Import Files

    Row 5 to row 8 starting at Column E are column headers. (highlighted In RED on the example documents).
    [list=2][/list] Each time a document is imported into the master Document the above is added as a new column at the end of the last column.
    [list=3][/list] I then need to match the imported data row to the store row in the list.
    [list=4][/list] The solution that the exports come out of the store numbers column is stored as a text and not a number.

    Any help appreciated on this.
    For some odd reason, one of my Mac clients started having problems connecting to my 2016 remote desktop server. Getting a message that says;

    We couldn’t connect to the remote PC. This might be due to an expired password. If this keeps happening, contact you network administrator for assistance.
    Error code: 0x207

    Password had no reason to be expired, but I changed anyway & low & behold i worked.
    Now, same user is trying to get back in & getting the same message.
