The memory pressure (yellow part at the bottom of the first screenshot) so I recommend upping your ram to at least 8 gigs of RAM (or even 16 if you can afford it). To see what kind of RAM you need, see HT1423 .
No, your MacBook does not need any "special" RAM. To see which kind of RAM is needed, visit this Apple Knowledge Base Article. It will show you how to replace your RAM and which one do you need. Although it is not needed to use two identical sticks of RAM, it is recommended, if your sticks are supporting Dual Channel.
This was asked before the public release of iOS7, so I assume you were asking about iOS6 or earlier. However, since it's not tagged for any specific version of iOS, here's the iOS 7 answer. As far as I can tell, the only way to do this is to put your podcasts in list view (not grid view). Swipe the name of the podcast you want to delete to the left to ...
Yes, Crucial Ballistix Sport memory modules with CL=9 timing do work. The results of an Xbench 1.3 "Memory Test": Hynix CL=11: 618.25 Crucial CL=9: 699.12 The not by Crucial recommended memory modules perform 13% faster then Apple's factory default modules in this Mac. Benchmarking performed on a 15" MacBook Pro (Mid 2012, MD103xx/A, MacBookPro9,1) ...
There's no exact equivalent that's distributed with Mac OS X, but there are a couple other ways to get the information: system_profiler - Shows all of the Mac's System Profile info in the shell sysctl -a | grep mem or sysctl hw.memsize (total mem)
For each process there is Real Memory (always at least as big as Memory) Total Memory currently consumed by an application (including Virtual pages) Memory Memory used in RAM Purgeable Memory Memory which can be cleaned by MMU, if another process needs more real memory. Then, for the system in total Physical Memory The amount of RAM installed. ...
virtual memory is basically free __ space used as an extension of ram
I'm wondering what you're seeing that makes you think you don't have free memory. The way that the virtual memory system of Unix works, you'd expect about 10% to show up as "Free" in the way Activity Monitor displays memory on a normally running system. (You need a little headroom in order to actually do the tasks of managing memory, so the operating system ...
There's nothing to solve here. You should learn about memory management. The OS will keep as much in memory as much it can even seemingly outdated data that might be needed again (think of undo actions, reopened browser tabs, etc.) However, if really needed to free up some memory, you can use the purge command in a terminal window.
The screen grab is from Activity Monitor. Most of the physical memory is used, if for nothing else, to cache data from the hard drive. If you had included the right side of the table in the screen grab you would see entries like "File Cache" and "App Memory", etc. which add up to the number for "Memory Used" on the left side.
It seems to be something to do with the service that renders icons in Finder, when mine maxed out cpu no icons were rendering in finder. I force quit the process and reopened Finder and all seemed well again.
In case you're only really interested in swap usage (what would be the last line of output from free): $ sysctl vm.swapusage vm.swapusage: total = 64.00M used = 0.00M free = 64.00M (encrypted)
The problem is with clearing inactive memory in the first place, regardless of which command is used to do it. Indeed, using purge is "not a good idea" but the problem is due to what the end result of the command is rather than how the command does it or other specific problem due to the command. Running purge attempts to clear inactive memory. An ...
It accepts it but won't let you use it while using an apple OS. It is clearly a software problem and it is shocking that apple will not give an update to solve this issue!!!
