This seems like a lot of work to me since your swap rates are easily measured and generally not at all the bottleneck that needs alleviating on OS X systems I've managed. Losing swap will be highly destructive to data integrity so you should have your system backed up regularly and able to be restored and files reconstructed if they become corrupt during a ...

Fusion Drive technology is part of the Mac OS itself. Windows cannot use it. It can, of course see the Core Storage Drive & its NTFS partition & boot from it, but it cannot use the hybrid technology underlying 'Fusion' itself. Bootcamp will make the NTFS partition purely on the HD. btw, Bootcamp is the only way to add the extra partition to a ...

If you're a pretty technically savvy, i don't think you need Fusion Drive because you could do it yourself. Invest in a 256 go SSD drive, divided into two partitions, one for each systems. Move all your heavy folders on your Terabyte (or more) HDD drive. /Users/MyUserName/Downloads /Users/MyUserName/Pictures /Users/MyUserName/Movies /Users/MyUserName/Music ...

In my opinion it shouldn't be a problem: delete the CoreStorage LVG (FusionDrive) and end with 2 seperate disks: the SSD and the HDD. Install Mac OS X on the SSD. use the Bootcamp Camp Assistant to install Windows 7/8 on the SSD partition the HDD according to your needs (HFS+ & NTFS/HFS+/NTFS) You will end with a partition layout similar to that: ...

Since FusionDrive is really Corestorage with some added magic (or supposed to), there is no mandatory reason to assign the whole SSD to the Fusion drive. When creating you DIY Fusion drive, just reserve space by creating adequate partitions and refer to the partition ID (diskXsY) instead of the whole disk.

Turns out resetting PRAM and NVRAM via pressing ⌘+⌥+P+R at boot (before the gray screen appears; hold until computer restarts and the startup chime has been heard twice). I have since successfully booted both OSX and Ubuntu via rEFInd without any excessive waiting.

the sluggishness may come from newer O/S upgrades that have degraded the performance of the computer. I say this because Mac O/S rarely has the "bitrot" issues that plague Windows, making it necessary (if not just advisable) to reinstall the O/S every 3-4 years. So if you have kept up with the O/S upgrades that may actually be the culprit. There are also ...

Take a single Time Machine backup, just in case. When you wipe the laptop, use the Time Machine drive to selectively (manually) restore certain items. Information and files related to application licensing will most often be located in: ~/Library/ ~/Library/Application Support ~/Library/Preferences

IN DISK UTILITY SELECTED PARTITION THEN MADE 1 PARTITION ADDED A NAME FOR THIS SSD PARTITION AND APPLIED. THIS DID THE TRICK. NOW I CAN SEE NEW SSD IN FINDER AND CAN LOAD INDIVIDUAL FILES AND ALSO SEE IN CARBON COPY CLONER FOR FULL CLONE BACK UP.

Before you can clone your hard drive with CarbonCopyCloner, you need to create a partition on the drive and format it appropriately for use with your Mac. Most external drives come pre-formatted for use with Windows machines. You can use Disk Utility for this purpose. You'll find Disk Utility under /Applications/Utilities/Disk Utility on your machine. In ...

iMac that spends most of its time reading and swapping files from the 2TB hard drive That sounds like a problem that needs to be addressed. 1) how do you know this is what is happening? 2) How much memory does your computer have? 3) if you are Terminal-fluent, provide the results of ls -l /var/vm

As you know with SATA connection you get 3 to 6 Gb/s. With Firewire you get < 1 Gb/s data transfer. To be specific: Firewire 800 is 800 Mbits/s (Mb/s) not 800 Mbytes/s (MB/s) [8 bits in a byte] its a common misconception. so Firewire 800 is rated up to 80 MB/s.

I guess you figured this out a year ago now - but you need a PATA -> SATA power adapter [couple of quid/bucks/shekels from Maplin's/Radio Shack etc] & run it from one of the old superdrive power-supplies you'll find ready & waiting in that bay.

I had this happen with rEFInd before. I think rEFInd boatloader ended up in your efi partition. The excruciating long wait is rEFInd checking every device/partition to see if it's bootable. I have the debug menu in disk utility enabled, so I just selected show all partitions, mounted the efi partition from available partitions in the top left window, and ...

Nothing that I can think of. My own experience was just - clone, test for a few days, decide all was good. Then, eventually retire the old drive for good. You might want to check that the new drive has the correct Recovery Partition in place before making the final swap. Disk Utility can tell you if the partition is present, if you set the Debug menu to ...

Here are some points from my Upgrade of my old iMac (late 2009, Model 10,1, #A1312) You can expect a significant Performance increase when starting Apps or saving Data, but overall-performance is depends on you RAM size too. If you are working with Photoshop f.e. you should def. have more than 8GB (on 10.10) - the more the better. You will encounter ...

your idea is charming, but does not work with your system. What you can do is to add a ssd and merge it with the hd into a fusion drive using Apples on-board tool residing within the disk utility. If you are running Yosemite it will be o. k to just start. if you are running Mavericks and willing to upgrade to Yosemite, DO THIS PRIOR ANY HARDWARE ...

I am currently going through the same thing myself. The SSD is not likely toast as some suggest. For my situation, I have installed a second 1TB SSD on my Mac Mini 2012. I tried with a 500GB one with no problems (except a defect in the drive), so I decided to upgrade to a 1TB. After installation, I could see the drive on Disk Utility but not format it for ...

You are safe to upgrade you HDD to a new SSD. The problems with unsigned kexts will only affect users with third party SSDs, upgrading from a lower OSX version to Yosemite, and having enabled TRIM using Trim Enabler. You have nothing you worry and, in case you decide to install Trim Enabler after the hardware upgrade, it will disable kext-signing checks ...

Simple way: Download Yosemite from App store (5,12 Go) Downloading you will asked where to install Yosemite. Replay (after connect) on the external SSD. It need between 20 and 40 minutes At the end the soft ask you if you want to import your data and from where You reply from your HDD The best way is now to installe SSD in your MBPro

If you're running OS X on a HDD then I don't see how TRIM enters the equation, since TRIM is only for SSDs. If want to do a fresh install on the SSD, simply install it and proceed with your bootable USB, I do not see the problem. What I did when installing the SSD was to put it in an enclosure, connect it via USB and use Carbon Copy Cloner to clone the OS ...

This is normal behaviour for Yosemite for users with FileVault enabled (i.e. Your Mac's primary disk is encrypted). The authentication process is done earlier because without authorisation from the user the OS cannot access the rest of the disk. This is a good thing, and I think you are (mostly) mistaken that it takes longer to boot up — since now you are ...

Copy your home directory over to the other drive. Open up System Preferences then the Users & Groups pane. Click the padlock to unlock it Right-click on your name Change the Home Directory to point to your newly copied one on the other drive. NB. You might want to use a syncing program to do the copy, or create a different user to do the copy as after ...

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 attempted to upgrade my late 2010 MacBook air with an SSD from OWC. The first one worked for 3-4 hours and then the system wouldn't recognize it. I RMA'd it. The system wouldn't even recognize the replacement. The original SSD continues to work fine.

I always recommend an SSD as an upgrade to revitalize just about any system. You will notice a performance increase with an SSD, though it will be mostly load times (we're talking a night and day difference here). You aren't going to increase your frame rate. Sure, it's true that your system doesn't have many more years (months) left in it, but if you buy a ...

Be carefull when working on an imac and ensure you have the correct tools - corrct size Torx drivers and a suction cup or two to remove the glass safely. Also use iFixit for a guide on how to do this such as https://www.ifixit.com/Guide/iMac+Intel+27-Inch+EMC+2309+and+2374+Optical+Drive+Replacement/1637 I would suggest a superdrive HDD enclosure.

IMO it is not worth if you do the math. You would come by for a short while with SSD + RAM, but soon to find out you do not have enough computing power. You would need to upgrade the GPU + CPU + RAM + SSD to bring it up to snuff to last you another 3-5 years. So what ever money you spend, it will not bring you up to today's standard and maybe only improve ...

More RAM will always give you a nice little performance boost but the real power comes down to what processor you have.

OK, as step one we need to clean your Network set up. It is generating to many Errors. Disable Sharing and iCloud and Bonjour. Try the simple approach by Deleting all your network profiles and then reboot without them. Check your connection quality to the SSID 'Desperate Housewifi' Next is to set a new network profiles (connections)- reboot again to see ...

OP, you can run the following command "diskutil cs revert" in Terminal. It will non-destructively revert Yosemite's unnecessary CoreStorage volume setup into a "normal" (non-CoreStorage) setup. I had to run in on a few of the dev previews. You may have to run it as root.

I don't think so. I put together a Fusion Drive as an experiment to see if was preferable to using a pure SSD vs. a high speed drive, and the trade offs, namely size vs. performance. With my Fusion, the SSD was on the inside of the unit and I was using a Firewire external drive. The nice thing was that when the Firewire's drive activity light flashed, I ...

I really doubt that the Update Software(Performance Restoration Software - ISO file)/Firmware file will help much.

Additionally Samsung advices to backup all your data on the SSD before updating the ...

When installing to a new drive, you first need to go into Disk Utility and partition the drive before it will be found as an installation target. Once you've created the partition, exit Disk Utility and restart the installation process. It should proceed as normal. You'll want to use Mac OS Extended (Journaled) as your format type.

On Yosemite you can use the command 'diskutil cs info' and the corestorage UUID as a parameter. There will be a line in the output table that shows "Fusion:". On my core storage volume it showed "NO". I have a 2011 iMac. Sure enough, performance led me to investigate this and all the test scripts and commands I found show that it was not a true Fusion ...
