The "store files on a separate disk" advice is for many reasons, one of which is getting an extra read/write head into the process. As SSDs have no latency, and bus speeds are many times faster* than they used to be, the main reasons are mostly no longer valid. It's still a good idea for other reasons, but on a Mac Pro an external Thunderbolt drive won't ...

Playing a movie, plugged into thunderbolt, and Photoshop is a lot of memory usage. Maybe you should change a CPU. What CPU is or?

Re-install OSX system using a TimeMachine backup The easy way is to reinstall OS X and restore using a TimeMachine backup. First make shure you have a Time Machine backup. Time Machine works with any hard disk connected to your computer using USB, FireWire or Thunderbolt. Select the Time Machine icon from the Menu. Select Open Time Machine ...

The difference is minimal, from my experience. When I made a fresh upgrade to Yosemite, I did some tests. I have 16Gb RAM, and 2 internal SSDs - one unencrypted, and one encrypted with FileVault2. On the encrpyted disk, there's a encrypted sparsebundle where Firefox profiles are stored. I can't remembered the numbers, but after comparing the read/write ...

An encrypted partition would likely be faster. With a disk image, you're actually accessing two filesystems, one within the disk image, and the one on which the disk image is stored, as well as the technologies needed to read the disk image itself. It seem unlikely that a disk image could ever be faster than full-disk encryption, but you would have to run ...

I would go with MacBook Pro for the better CPU, GPU (iris vs HD), and screen resolution since you are going to work with photo and video editing.

Go for the MacBook Pro. It'll handle better video editing and photo editing software, and it's more powerful speaking about CPU. It's built for professional worker and who need performance. Another good point is that you will be able to upgrade RAM and SSD in the future, which is not true for the MacBook Air (they are soldered). I've got a MBP 13" mid ...

All third party apps on the Watch currently are going to be slower than grabbing the iPhone, unless you can't get at the phone due to social constraints or it being inaccessible in a bag or pocket or some distance from you and the watch. This is because Apple has made every effort to let no code run on the watch at release. Third party apps get to run ...

Anything below 10.10 the newest system has so much disk I/O it could fry the older hard drive.

I do have the same iMac as you. I believe Snow Leopard is the fastest system you can install in your iMac though its not supported by Apple anymore. I did the upgrade to 10.9 and I felt the system slower, but, I did that because some softwares required the upgrade to run. When Yosemite came your, I gave it a try. I made a fresh install and, at ...

It could help if you see kernel_task soaking CPU cycles. From https://support.apple.com/en-us/HT203184 Activity Monitor may show that a process named kernel_task is using a large percentage of your CPU, and during this time you may notice a lot of fan activity. This process helps manage temperature by making the CPU less available to processes that are ...

I currently use a maxed out 11" MacBook Air which gets 10+ hours out of browsing with Chrome, with music playing from iTunes or YouTube most of the time. It can handle GIMP and Photoshop, video editing (tested with iMovie) and development with Xcode, Eclipse, Komodo and Brackets. I have experienced no problems with running games on High graphics settings ...

I have a 2008 iMac 8,1 Core 2 Duo running OS X 10.10.4 Yosemite. Yosemite actually consumes less HDD space and appears to run faster than older versions of OS X. My recommendation is always upgrade to the latest OS. Note also about two years ago replaced original 1+1GB RAM... now have (2+4) 6 GB 800 MHz DDR2 SDRAM. Works beautifully.

You might want to try the software "disktester." It has a recondition function that apparently works with SSDs. I haven't yet tried it myself, but it looks pretty legit.

This is how I fixed this problem. It might help you but from what I've seen so far, even thought there are similar issues, the source of problems are different. I've ran sudo iosnoop -n quicklookd - it shown something like this: UID PID D BLOCK SIZE COMM PATHNAME 501 5656 W 56385320 32768 quicklookd ??/Quick ...
