Rember mac os x 10.4

If you can't, there's a good chance the RAM chip you pulled out was the culprit. If you can reproduce the issue, chances are the pulled memory wasn't the cause.

Assuming you've got more than one RAM chip installed, repeat the process, reinstalling the "tested" chip and then removing a different chip each time, until you've either found the bad module or eliminated "bad RAM" as the cause in which case it's time to move on to other possible causes. Unfortunately, if the only memory in your Mac is what came with it, and you don't have any spare RAM chips to swap with that memory, then you can't use the above testing method.

It's also difficult to use this method if your problems are intermittent and unpredictable -- if you're experiencing kernel panics or system freezes that don't seem to correlate with any particular action or event, you can't determine if removing RAM or swapping it out fixes the problem. Or perhaps you've got a lot of installed RAM and you don't want to go to all the trouble of testing each chip separately.

What you need is a way to test your RAM just as you would test your hard drive using Disk Utility or a third-party utility such as Alsoft's DiskWarrior. However, for whatever reason, it's possible for bad RAM to pass these tests. Thankfully, there's a much better solution available, and it's free: I'm not going to get into the nitty-gritty of how Memtest works; to put it simply, Memtest writes data to chunks of RAM, and then reads that data back from RAM to verify that it's the same.

If it isn't, there's a problem. If it is, even after many, many testing cycles, it's a good bet that those chunks of RAM are good. By testing every chunk of a RAM chip in this manner, Memtest gets a pretty good idea if the chip is good or bad. There are several ways a memory-testing utility can verify data saved to RAM; Memtest uses multiple methods in order to test thoroughly.

Memtest has proven to be so good at what it does that I consider it a must-have troubleshooting utility -- one of the first things I do when I'm having serious problems with a computer is use Memtest to test the computer's installed RAM. I also recommend using Memtest whenever you add RAM to your Mac; after all, you may as well make sure your new RAM works properly before trusting it with your data, right? If you don't have much Unix experience, once you've downloaded and expanded the Memtest folder, you may be a bit intimidated -- it contains a number of Unix executable files.

But don't fret; it's actually quite easy to use. Unix gurus may prefer to install Memtest elsewhere; either approach is fine. The former is easier; the latter allows Memtest to test more of your RAM.

When booted in Mac OS X. Note that 4. Terminal's output will show you the results of each test Memtest performs as it occurs. Once all tests have completed -- which can take quite a while if you have a lot of RAM -- you will hopefully see the message, "All tests passed. However, even if you get the "All tests passed" message, the developer of Memtest recommends running Memtest at least 3 or 4 times in order to ensure that your RAM is indeed problem-free. For Mac OS X It makes "typing" of unusual characters easy without having to remember keyboard combinations.

Click the "P" in the system tray to display a table of characters. Menu shortcuts are supposed to provide quick access to frequently used menu commands. Honestly though, how many shortcut keys do you know by heart? KeyCue helps you to learn and remember the keyboard shortcuts of the applications you are using. Over time, you will automatically remember frequently used shortcuts and start working more efficiently. Have you ever experienced the tedium and frustration of having to repeatedly type your name, e-mail address, home page url, or other words or phrases again, again and again?

Typinator boosts your productivity by automating the process of inserting frequently used text and graphics and auto-correcting typing errors. PopChar X PopChar makes "typing" of unusual characters easy without having to remember keyboard combinations. VM size is usually somewhere between 10 and 20 GByte on my machine most of the time, and that's without much going on. Finally, have Activity Monitor running and have the little CPU "speedometer" up and placed in a corner of your monitor so you can see what is going on during the beach ball show.

May 31, My Machine: For example typing into test edit, while Firefox is open with one window. Or, I open a window in Finder and it takes 15 seconds for the request to complete, meantime all other applications freeze in those 15 seconds. Nothing works and I have 2 GB ram! When problem started, I had a pro optimize the system - Checked all 3 HDs. I have booted into 2 different drives and have the same problem: Beachball appears often.

When opening windows in Finder, it hangs for about 10 seconds. Sometimes it just stays rolling until I force shut it down. Every session it happens at some point. I don't need to shut it down every time, but, it is slow, as if a huge program is running in the background. BUT, I only have the browser open. It scrolls with a stutter often or beachball shows up when opening a new tab that is loading a page. For the Primary Drive which is GB capacity: Disk Usage - Space utilized - This happens even when there is no browser or when I use Safari.

I'm deeply frustrated, as I can't work profficiently on this machine right now, and it's the only one I have.

The memtest app is on my desktop I have super duper and I love it. Will get Disk Warrior. I will have console and activity monitor open at all times, Only reason I think it's possible bad ram is because the freezes are happening on my other drive as well. I get slow window beachballs when I boot into it! That'd be looking at the root of the drive for it I believe, I think you need to cd, change Directory to your Users folder first , or if using Terminal then Boot from clone and then repeat the repairs on your primary drive.

"Specific" command for memtest in termina… - Apple Community

I prefer to have a 3rd Mac OS boot drive only used for repairs and maintenance, not for anything else, but which has my utilities and fully updated, just doesn't have 3rd party apps and anything that is non-essential. Use to be that iTunes was one of the best triggers to catch memory error for some reason back when around iTunes 8 or earlier. Sigh, I worry about losing stuff when doing a restore, eps in the middle of a project.

But, seems the best thing. Guidance please: There us much I don't understand or have experience with and don't want to lose valuable project files. When cleaning out and doing restore is this the same as a fresh install? Which means up-dating off the net once again? Means resetting my password as well? What is the best way to replace all my folders and browser prefs after this? Drag in from clone and place Don't want to create a system mess for dropping in the wrong place If you have anything importsant or irreplaceable, you really, really want a backup or two, especially before trying installs or repairs, though DW is vert good.

I have 2 usb externals. A Seagate gb and a Hitachi gb. I was told the MDD may not have enough power to keep up 3 internal hard drives, hence the freezes.
