Part of the issue is that low priority input/output-operations (I/O) now seems to get throttled heavily. You can check it via Terminal (can be found via Spotlight ⌘Space and entering terminal) then entering at the bash prompt: fs_usage backupd and look for the THROTTLED entries. If you see them, the backup is throttled. So if you have a ton of files, ...

You could probably go with your 1st option from an Apple Service provider or DIY, but Apple doesn't upgrade storage on any shipping Mac. The last one to offer that was the Mac Pro which had no-tool, user swappable hard drive bays. Your 2nd option will tie your laptop to the network providing the NAS for full operation. You would want an iSCSI initiator for ...

All the files are still there, you just can't get at them since the mount point has changed the system's ability to resolve files in /Users/whatever (a.k.a.~) Going forward, try mounting the drive under /Volumes (as in sudo ext4fuse /dev/disk2s7 /Volumes/myDrive) You should probably reboot the Mac since many programs will have issues saving work to the ...

'Bird' is part of the iCloud structure. You would have a large cache if there are pending documents to upload or process. Over time, com.apple.bird cache is generally kept cleaner than your singing. Mine is 400 KB [that's K, not even M] You can diagnose this with brctl - which has a diagnose command and a log command. Unless you are sure you have a bug in ...

I have the same model of Macbook which was showing the same issues. After replacing the Harddrive with an SSD I still had the same issue. It ended up being the SATA cable connecting the hard drive to the logic board. Over some time the insulation had started to wear off and the cable was occasionally shorting against the base of the case causing IO errors. ...

I found this worked perfectly (from the terminal): diskutil eraseVolume ExFAT MyName diskX You'll need to change diskX to whatever the number is for your drive. You can find that out in disk utility, select the drive, click info, and look under 'BSD device node'

The method to repair your disk and recover the GUID partition table is related to my answers to similar questions: HFS+ invalid number of allocation blocks and Hard drive no longer accessible. Basically you have to find characteristic strings of JHFS+ volumes, use some simple math and common sense and have some luck to fix the GUID. And don't loose sight of ...

Download the installer to the current system While it downloads, partition the SSD as GPT/OS X Extended Run the installer and install the OS onto the SSD instead of the current boot drive Use Startup Disk preference pane to set the new SSD as the boot volume default - NVRAM points to the SSD for all subsequent boots

With Apple's OS X tools you can't expand the start sector of a partition to lower sector numbers. You have to choose another method. You may accomplish your objective if less then one half of the net capacity of your hard drive ((~disk size - size of Recovery HD - size of EFI)/2) or less then one half of the main volume is occupied. If you miss the ...

Make sure you have version 14.0.382, previous 14 versions had that problem. I had this problem with the version I downloaded from the Paragon free upgrade link. I solved that problem by downloading the 14.0.382 from their website. Strangely the new version didn't show up clicking the "check for update" button on Paragon NTFS preference pane.

The maximum allocation block (or cluster) count for exFAT is 2^32 = 4,294,967,296. To get the minimal size of an allocation cluster on your partition divide the size of your partition through 2^32. Examples: for a 100 GB partition the minimal size is 100,000,000,000 bytes/4,294,967,296=~23.3 bytes. Since the smallest device block size is 512 bytes, the ...

It all comes down to your convenience. The MacBook Pro (MBP) uses a proprietary interface for their SSD; PCIe 2.0 x4. This is why they are so expensive as you have noticed. Upgrading the SSD in the MBP to a larger SSD, whether you get it at time of purchase or you get it later on, is going to be an expensive proposition and the only reason that you do ...

You can "restore" to a new Mac during setup from a Time Machine Backup. This would be the most straight forward solution, but it won't let you selectively pick and choose what to restore. An option still involving Time Machine would be to exclude locations that you don't want to backup and restore fully (such as the Applications folder) and just backup that ...

Not possible. There's not enough room for a spinning hard drive to be connected inside any retina portable MacBook. That being said - hose drive would work well externally via thunderbolt or USB and internal non-OEM replacements are available. To install special SSDs. other than Apple branded look for resellers and online like OWC or RamJet.

As far as I can see both MacBook's using different SSD's. Take a look on iFixit.com and the image taken from the tutorial MacBook Air 13" Mid 2012 Solid-State Drive .

You can use an external hard disk formatted with HFS+ as a Time Machine target for several Macs without problems. Time Machine itself will make sure that the data is not getting mixed up by using the name of each Mac as part of the path.

If you replaced your HDD in your iMac with a new SSD and you try to boot, nothing is going to happen. I am assuming you are getting something that looks like this: That means your iMac can't find anything to boot off of because your new SSD is completely blank. (You just took it out of the box and exchanged it with the old one, right?) Command + R doesn'...

I have the exact same problem and to the best I can tell, it's the chipset used in the OWC Mercury Elite Pro minis. Very disappointing. My 500GB 840 EVO works fine in these enclosures, but I've bought and returned two 850 EVOs thinking they were DOA. Suspicious after the second one, I spoke with Samsung support on 5/12/15. The rep immediately acknowledged ...

I'm assuming you have nothing on the new disk and essentially want to mirror what is on the old disk to the new disk. You can use the following command line, substituting the proper names for Source-Disk (old) and Destination-Disk (new). rsync -xavH /Volumes/Source-Disk/ /Volumes/Destination-Disk/ Note: The slash at the end of each path has significance, ...

This is the result of excess force squeezing the wrist pad against the internal components. In your other question asking about heat stress is a no go. Aluminum doesn't weaken or deform that way in temperature ranges where plastic won't melt and batteries don't catch fire. The bulge in the other question is really compression bending the case inward and ...

exFAT is not optimal for your situation probably, but unfortunately there isn't really a no-brainer solution for using an external drive frequently with both OS X and Windows, reading/writing large files, and with really low risk of data loss. exFAT is not a journalled file system, so there is higher probability of data loss than with NTFS or HFS+. exFAT ...

If you boot to the Recovery Drive (restart holding Command and R) you'll get a window with an option to "Re-install MAC OSX". Choose this and then choose your SSD as the target. When installation is complete, go to System Preferences > Hard Disk and select your SSD as the boot drive. Alternatively, you can reboot holding Alt/Option and you will be asked to ...

You can simply put an Apple Time Capsule in your network and select this as Time Machine backup volume. And you may choose an encrypted backup to ensure more privacy. This works perfect in my office with a dozen MacBooks. A more cost efficient solution may be a 3rd party solution like a Synology DiskStation containing a Raid 1or 5. Synology also offers Time ...

Install a copy of the OS X Server app on a spare Mac with a pile of storage connected to it. Create a share for each Mac that you need to back up, and connect each Mac to its own share. That way, each Mac only sees its own backups. You can also limit the size allowed for each share if you like. Another advantage of having an OS X server on the network is ...

Depending on your MacBook model, removing the hard drive may void your warranty, so it might be better to prediscuss this with the store or ask them for other options. They may also offer you a way that they can do the backup for you (at extra cost maybe) or give you the old hard disk back after getting your MacBook working again.

The second part of that statement "or all flash storage" is universally true. Solid state storage that ships with the current (2015) lineup of hardware is almost an order of magnitude faster than HDD technology. If you can make a justification that the increased performance is worth the uncharge then a pure SSD storage chain is a first choice/no brainer ...

I confirm that the command: sudo sysctl debug.lowpri_throttle_enabled=0 works perfectly. If you want to make it permanent across reboot, you can do the following. create a file under /Library/LaunchDaemons/fix-el-capitan-slow-time-machine-speed.plist <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "...

I have had good luck by booting into recovery mode and using Disk Utility to clone the drive before doing major OS X upgrades. The steps: Plug in your USB drive. Boot your Mac into recovery mode by holding down command+r from the start of boot. Once the recovery menu comes up, select Disk Utility and click Continue. Select the drive you want to clone and ...
