The following diskutil cs resizeStack command is vastly undocumented and as such potentially destructive. There might be an easy way outlined first and a long winding, time consuming hard way. Please backup your Mac OS X before proceeding. The not-as-long-as-expected way: A 2nd computer or an iPhone with the stackexchange credentials to enter the site ...

The phenomenon derives from a faulty Apple Script mounting a Time Machine sparsebundle image from a smb-share serving as a Time Machine backup volume to /Volumes. The mounted image interferes with (maybe any) other mounted volume(s) there The faulty Apple Script: try mount volume "smb://someserver/DATA" end try do shell script "/usr/bin/perl -Ue ...

Ha, found it! It was a corrupted ".Trashes" folder in the root of the SSD. It occupied me than 100GB of data (see screenshot). I managed to make these files visible by running GrandPerspective from the command line: sudo GrandPerspective.app/Contents/MacOS/GrandPerspective That will show the files but still it is not possible to delete them. Even sudo ...

I have run Mavericks/Yosemite on a 64 GB SD card and after a clean install, there was about 20-30 GB free. I would say that you could install Yosemite on a 20 GB partition, but I would not recommend anything less than 30 GB.

Instead of rebooting constantly to test software in different environments, try a virtual machine. I use VMware Fusion. Major advantages include suspend rather than shut down, and you can have as many as you have disk space for. You can have as many running simultaneously as you have memory for, and you don't need extra hardware to handle different versions ...

With the encryption process included in Yosemite there is a duplicate drive created in the space after the drive that was encrypted. If I'm entirely honest I don't know how that works or what its purpose is I just know that every encrypted machine in this situation has it. That being said you can see using diskutil that your ssd does have a recovery drive on ...

I did fix this by resizing (making it a bit smaller) the Partition1. After doing this I was able to delete/resize all the other partitions. Well, I have no idea why this happened, so this is not a real solution but probably a bug of diskutil.

I am not an expert in OSX partitions but I suspect Carbon Copy Cloner mucks up the partition table somewhat so that start and end cylinders are not correct, or something like that. I may leave my new SSD as it is exactly the way you did it, or try Mike's (Bombich) suggestions to manually create the partition. By the way, they have released version 4 of ...

Troubleshooting Time Machine against a Time Capsule is a very slow process. I like to just get a new USB drive and let Time Machine back up there and you can know if the problem is the Mac or the destination. Doing that will help isolate what is causing the delay. I would also use a second machine to go into the Time Capsule and delete any "in progress" ...

This Mac Book Retina was originally delivered with Mountain Lion. The upgrade history contains Mavericks, several Yosemite DPs and finally the Yosemite GM Candidate. One of the Yosemite Developer Previews transformed the previous Apple_HFS partition into a Logical Volume Group. The (only) Logical Volume is not revertible: The Boot Camp assistant can't ...

There is a simple way to find out who is the owner of the computer as reported to Find my Mac. In terminal use nvram -p | grep fmm If it is your name there then you are fine.

The Boot Camp Assistant will move any file (if any) which may reside in your future Windows partition to a appropriate position in your then shrinked Mac partition before creating unallocated disk space in the repartitioning process. Therefore there is absolutely no need to defrag in the forefront. Please read Do partitions on SSDs map to physical addresses? ...

There are at least two approaches to solve your problem: One is potentially destructive, vastly undocumented and i don't know if it works (1) and the other one is for sure destructive (2). So please backup your Mac OS X and your Ubuntu partition if necessary. Requirements: USB thumb drive with a full working Mac OS X and iPartition installed or a Linux ...

Unmounting the 'unwanted' partition before installing the new application should help in most cases: Quit all open applications Start Terminal.app and enter diskutil list output looks like this: #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *121.3 GB disk0 1: EFI 209.7 MB disk0s1 2: Apple_HFS Yosemite 60.2 GB disk0s2 3: Apple_HFS ...

The easiest way (depending on your model) is to do an Internet Recovery. You can do this by holding Command+Option+R while your computer boots. You will get a globe and will either ask you to connect to Wifi or if you are connected to ethernet you will just see a progress bar. After it downloads it will bring you to the recovery partition and you can ...
