As bizarre as it seems i just installed Mav and then had all the probs listed here- so i ran a repair permissions on utility and now it seems fine- 1GB out of 4 is spare on average use- Memory Clean is a big help in spring cleaning RAM of any unnecessary use :-)

No you can't add ram to that model. However, the computer should be freezing. There may be hardware error, take it to an apple store.

I've just gone through two brand new MacBook Pro Retina 15's, "fresh" from Apple Store, both of which were giving me only 3-4 hours on a fresh charge. After resetting NVRAM and SMC, I now get 5-6 or more hours. If you buy a new MacBook -- and are getting less than 5 hours per charge -- try resetting your NVRAM and SMC. How to Reset NVRAM: Shut down the ...

It is unclear to me but did you replace the keyboard with the defective "w" or does the replacement keyboard have the "w" issue? The reason being, holding down a key, any key, will cause strange things to happen. An electronic issue with a Mac's (or really any computer's) keyboard can cause all sorts of strange problems. Can you disconnect the keyboard and ...

I would test the RAM to make sure it isn't faulty. There are various applications to let you test your RAM. Memtest is a free one you can download here. Just run the installer, then open a Terminal and type "memtest all" to run the test. It will run the test multiple times and might take an hour or two to run completely, but it will tell you if it finds any ...

Did you buy the RAM from a provider that guarantees it for Macintosh systems? I've gotten RAM from a big box store that has met the exact specifications, but wouldn't work in my Mac Book Pro without crashing all of the time. I ended up returning that RAM and getting it for about the same price from a vendor that guarantees it will work in my specific system. ...

Figured I would update this post long after. With Parallels 9, there is no longer the non-sensical recommendation capped at 4GB:

The clearest way I can see to see whether data is being paged in or out of RAM is the command line program top. Open a Terminal and run top. Within the first few lines of output look for "swapins" and "swapouts". The values at the end tell you how many pages have been swapped in and out of memory. The values in the brackets are the delta for that update ...

Thanks to all the posters and commenters, this has been a instructive and useful thread for me. My recent experience might be useful to someone. I use my Mac Mini with OS X10.8.1 and with 16G RAM entirely for prototyping software that will be run elsewhere. I can assure you that I will not "go back to Facebook in a few minutes or re-launch Word after ...

Fontbook was the cause for me, running at 3.9GB and kernel_task at 9GB. Force quitting fontbook caused the kernel_task to drop to 1.12GB and give my fan a break.

I just put a Crucial MX-100 512GB in a 2011 model and was impressed by the performance. Measured faster than the Samsung 840 in my 2012 model. It came with the spacer needed to fit the 7mm drive snugly into the 9mm space on the MBP. If you are going to the trouble to add memory, you might as well spend the extra $75 and go to 16GB.

As long as you can confirm the laptop is indeed from mid-2012 (later models have the memory soldered in), then these specs should work for you with either a 13" or 15" laptop (Apple started soldering memory in 17" laptops after 2011): 204-pin PC3-12800 DDr3 1600 MHz type RAM (Found at http://support.apple.com/kb/HT1270) As far as hard drives go, I'd ...

-What happens if you take the memory out and replace it with the original RAM? Does it work? -Have you tried re-seating the RAM? (e.g. take it out and put it in again, making sure it's fitting in the slots properly, and also making sure there's no dust on the RAM or in the slots...) -Is the RAM PC5300 DDR2 ECC? -Have you tried resetting the SMU? ...

Does that memory act as the "VRAM" that Final Cut Pro needs? The integrated Intel Iris graphics chips contain onboard memory that act as L4 cache this helps speed up access to the shared system RAM, but doesn't replace it as the backing store for graphics data. Does this mean that the discrete graphics card has 256MB on its own, but can also receive ...

I know your post is from a while back, but if this is still an issue, try my suggestions in this post. If those don't work, D.W. posted some other useful links in his comments. Hope you get this worked out :) Vlad

The app in this post is similar to the old OSX 10.8 RAM-pie-chart that used to show how your RAM was being used. If nothing else worked, run this program and see what colors it's showing. Lots of blue = a lot of files and apps are being cached into ram. Lots of yellow/red = some programs are being memory hogs. In either case, I have some more suggestions ...

I have two other suggesting that also helped me fix issues that I was having. Both of them are pretty easy too (no need to mess with any system files or change plist or anything else like that). 1) Go to the Disk Utility app on your computer and press the buttons in following picture in the order that they are numbered. This will make OSX scan your hard ...

I'm not familiar with the vector that you mentioned, but I think I know how to fix the problem with your kernel using a lot of memory. I found that my pc uses way too much RAM too whenever I have a lot of icons on my desktop. This also happened when I have few files, but they are large in size. As far as I understand, this happens because OSX pre-catches a ...

Adding application software will have no effect on the performance of your computer unless 1) the software is running or 2) it installs persistent background processes that consume resources. LaTeX does not do #2, so you need not worry that this will affect your computer in any negative way.

No it is not enough to have 4GB, since it is minimum you can have and you will always run at max of it. Mavericks will do the best to manage the space, but there is a limit what it can do. Big RAM users (aside of the OS) are the web browsers. It is all dependent what is your activity, apps you use. As said Mavericks will do great job in working your RAM ...

Can you boot into Mac O/S? If so open up System Profiler, click on the memory option and see what the Mac is seeing. If it sees all 8GB then the issue is with windows and you might want to ask your question on superuser or another Windows forum. If the mac side only sees the same 4GB then you may have an issue with the DIMM. It could be not seated properly, ...

From iMac (Mid 2010: Memory specifications): The iMac (Late 2010) computers have four SDRAM slots in the bottom of the computer and come with at least 4 GB DDR3 SDRAM installed as two 2GB DIMMs into two slots. The maximum amount of RAM you can install in your computer is 16 GB (a 4 GB SO-DIMM in each slot). You can use any Small-Outline ...
