2 GB of RAM is really low for OS X Yosemite. Though Apple says it is OK, I wouldn't do Yosemite unless my Mac had at least 4 GB. My iMac actually has 8 GB. Anyways, if you still want to go ahead fixing Yosemite, try applying some of the fixes given in this link here. Some are pretty solid. http://machmachines.com/mac-slow-yosemite-update-fix/

The memory for the MacBook Pro 8,1; 8,2 and 8,3 is the same as for the iMac 12,1 and 12,2. Just as a point of clarity, the models possible are: Early 2011 MacBook Pro Late 2011 MacBook Pro Mid 2011 iMac Late 2011 iMac

Plug your device into your computer. Download the app iFunbox. Go to the root file system, then open the directory "Application Archives" then delete all of the ipa files.

The answer is, make sure that your SSD has adequate power. Some USB cables come with two USB plugs at one end. The second and thinner part of the cable is needed for power supply. So plug in both ends one in each USB port of the computer and then it should supply enough power. Alternatively, and this made for a more reliable power supply, one can use any ...

I'm having exactly the same problem and i tried everything just like what you did. at last i brought it to apple care and it was the hard drive. it seems that our mac version is having problem with this version of osx. i replaced my Hard drive and every things runs back to normal

it should work. i would just make sure you can return it just in case. when you put the new ram in the mac will beep if the ram is not acceptable.

Before reseting everything, you should check to see if your friend has Speech Recognition enabled. If so, it could be eating up 1 GB of RAM! Why does speech recognition take up 1 GM or RAM suddenly? And GMail in Safari 738 MB?

While Apple says you need a minimum of 2 GB RAM and 8 GB of disk space, those are the minimums. I would recommend adding RAM to speed things up. (4 GB would be just enough, the more the faster). Look up your model and get it if it is not MacBook Air. (no upgrade for MacBook Air). You are correct, there is no formatting, but to speed up the hard drive, use ...

Since Yosemite needs drivers for those and it has to be signed(here is discussion of possible problems with that kind of SSD on Apple discussions) you much better off installing SSD inside the MBP in place of HDD. Here is instruction from iFixit how to do it.

The answer is 'Yes, it will take them.' 8GB sticks were 'unsupported' at that time, but just turned out they worked. I have an old Mac Pro that has the same 'unofficial' double-storage. Shoudld take 32GB 8x4, does in fact take 64GB, 8x8. It's only the 21" iMac from that series that really can only take 16GB Ref - Everymac & personal experience. For ...

I ran into this problem recently while attempting to install a Mountain Lion VM on my Mac Pro (10.10) using VirtualBox 4.3.2. I was trying to follow the instructions here, but I got stuck in the EFI boot sequence. I attached a screenshot, but I think its where you got stuck too. I tried the same process on my macbook pro laptop (with the same iso), and ...

While hard drives are the most likely component to die in any computer, memory can and does fail from time to time. An "Early-2011" model will be nearly four years old now so it's worth considering an HDD replacement at some point (these were some of the first systems to feature SATA-III controllers so you will be able to take full advantage of current SSD ...

I'll make it quick for you : MacBook Pro and MacBook Air have the ram now soldered to the main board. You won't be able to upgrade the ram on the new MacBooks.

I can't find an exact diagram for the iMac, but assuming the mapping is anything like my Mac Pro - which really surprised me when I first tried it, the top & bottom slots may not be as you expect. I would certainly experiment with identical RAM first in top or bottom, but I would also try matching them top to bottom row ie… 2 2 8 8 8 8 or ...

The overall picture of your RAM is that it's healthy and there is no memory pressure. Something else is the bottleneck causing slowness. Onle 2 GB of RAM is used for App Memory and less than a gig of File Cache and Wired Memory seems fine. Some IO would be faster if you had more File Cache, so you could try quitting Apps you don't need, but I'd focus on the ...

Not really sure whether this is truly an answer to your question, but this Applescript works for me, run as an App. set RAMDisk to "RAM_Disk" as text tell application "Finder" if not {exists disk RAMDisk} then set VolumeName to RAMDisk set SizeInMB to 1024 set NumSectors to ((2 * 1024 * SizeInMB)) set DeviceName to do ...

I really think your best option is to take it into an Apple-licensed fix-it person and have them open it up. I expect they'll find some kind of damage on the motherboard (probably up and around the underside & top). Water does some gnarly things to electronics, so just because it's still turning on and 'working' doesn't mean there isn't something damaged ...

It is the Smith of OS X, a result of the equation trying to balance itself out. ;)

Processing speed (and the processing speed of the graphics processor) also have a huge impact on the snappiness feel of a computer. Using activity monitor, check how much ram it is actually using. If it is reaching %80 used then a RAM upgrade makes sense. I have a mac-book pro with 4GB which I bought used. Yet it feels fast. It is even older, being from ...

If I were you I'd update the RAM to 8GB (Apple says 4GB is the max supported, but you can go to 8GB) and install Yosemite. Without updating beyond 2GB, I would try either Snow Leopard, or Mountain Lion. The downside of using the older OSes is that they are unsupported, so you won't get security updates.

You basically have two options: If you don't want to open up machine then install Snow Leopard as leanest of them all. It will be fast though few resource hungry apps or web pages can bog it down. Another minus of the path is that Snow Leopard being released July 25, 2011 is going to be unsupported soon if not already. At least latest NTP patch doesn't ...
