IMac G5 1.9ghz OS 10.5.8 512mb ram

I have finished fixing a imac g5 1.9 with 512mb ram for my 8yr old daughter. it seems to run fine, but it tends to freeze a lot requiring a reboot. I also see in the Activity monitor that the CPU usage tends to be maxed out for quite a while after the re-boot. system % is low but % user causes it to max out even though I do not have any applications running. after 5 min, it seems to calm down.
Now I do have a 2gb stick of ram on its way. should the memory put an end to the freezing?
thanks
Kevin

512MB is the minimum required for Leopard, and with most operating systems, the minimum is enough to turn on the lights, however, certainly not maximize performance. Although it resets at each boot, you could view your page ins and outs on the system memory tab of the Activity Montior to see what's happening with 512MB memory. If page outs are 10% or greater of page ins, you can use more memory for what you run. Your 2GB on order should certainly help in that respect.
Assume you have plenty of free space on your hard drive for systems usage (10% or more).
Do you have any print jobs that haven't completed? OS X can max out trying to reprint ... maybe a long shot but worth checking. dd

I have a problem with Imac mid 2010 graphics card (ATI Radeon 5670 512MB)

I have a problem with Imac mid 2010 graphics card (ATI Radeon 5670 512MB). When I play video formats like xvid, mkv, avi iMac freezes and emits horrible sound,in service said the problem is not overheating. Not a problem with memory or hard disk because I placed second correct parts.The same problem is with OSX 10.6.8 and 10.8.4 and other players.Apple hardware test found no problem and tech tool pro found no fault.
After five days of testing in the service they can not found fault and it was decided to change the graphics card.
New graphics have been tested for two days but it is not reproduced divx ... but their test software which did not find any fault on the old graphics...
Do I have the right to complain if repair does not fix the problem because I use non apple softwere and video formats.

You could look at the System Profile for the info it presents for the card. But why wouldn't you think it's not up to date if you have the latest install (according to your sig above)?
What program are you trying to run? Is there anything in the system log?
I think it's the program that's having the problem and not anything with your video software.

IMac 8.1 3.06 GHz w/6 MB Ram, Lion and dead HD? all I get is "Gray Screen w/wirlie gig" but now for a new twist a circle with a diagonal line, like don't go. Is this a DEAD HD?

          I have a iMac 8.1 3.06 GHz w/6 MB Ram, and was running Mac OS X 10.6.8. My 500 GB WD5000AAKS was about 90% full. I had an issue with the admin password, it would not accept any of my known passwords. I ran for a while on the fingerprint reader I had, we have two users on the machine in our home. I tried many attempts to fix this problem without success I came up with a plan. That plan was a new HD, used a 2TB Samsung. plan worked like a charm. Installed a 4 GB Ram Chip and the new Samsung, formatted it, loaded Snow Leopard, and loaded what was on my Time Machine backup all was good.
          This was early July, then Lion was available I was happy with what I had, I had 1.450 TB of free space. So, what the heck, lets spring for Lion, that even went well for a not even 2 weeks, enough that I had several Time Machine backups.
           Then monitor goes flash, flash then I try a re-boot same gray screen with whirlie gig that I had when the the HD in my MacBook Pro died. Put the old 500 GB WD back in and all was fine, ran for a day. It was OK except back to no password and full. Went down to my local computer shops here in Rayong Thailand and sprung for a New 2 TB WDXXX, put that in, used my Snow Leopard disk to format and load OS X 10.6.8. I though that all was good, the load from Time Machine was slow and the time remaining was changing all the time, took about 3 hrs for about 300 MB that where on the LaCie.
          Now I have a password issue, however it asks for a password reset that it will NOT take and I don’t even get that now. All I get is the infamous “Gray Screen w/wirlie gig” but now for a new twist a circle with a diagonal line, like don’t go. Is this a DEAD HD? I plan to re-install the old 500GB just to systems check and if all is well I will take the “NEW” 2 TB WD back for replacement. I am thinking that I should put the new HD in and format and load Snow Leopard then up date to Lion then do my Time Machine backup. The only problem is does the circle with the diagonal line mean something more? If so how does one recover Lion with no disk if that is what I need to do. Yes, I have tried control “R” on boot, nadda, no response, “mai dee” no good. Ideas, please.

I have an iMac 8, 1 that I upgraded Leopard to Snow Leopard. It was totally updated with the latest from Apple when I bought and tried installing Lion. The upgrade failed, shot my OS and I couldn't boot. Had the constant spinner on a grey screen.. did a format of the drive, hdd repair and everything came back clean... got back to Snow Leopard and all the updates on it again and then retried the Lion thing... same bs... dead duck. Crashed my system one too many times. I can't see where a few small changes, mostly app related can be classified as an OS upgrade and is not compatible with my iMac. I have the stuff running on my Mac Pro but have yet to notice anything impressive. I've always used F3 and really didn't require Mission Control. Just open you app folder for launch pad... duh? I use the hot corners anyhow. As far as Safari is concerned... as a power user, Apple missed the boat on that for me.. full screen etc.. Wow. I don't like the new Mail either..
As you can see/read, I'm less than impressed with this release from Apple but I own so many of their products that I will have to put up with it for now... somehow the MS logo should apply to this release Steve.

IMac 2.4GHz (MA877LL) refuses to boot with 4GB ram, boots only with 3 GB

iMac 2.4GHz Core 2 Duo 20" Anodized Aluminum (MA877LL)
iMac 2.4GHz (MA877LL) refuses to boot with 4GB ram, boots only with 3 GB
2 x2GB Geil GX2S6400-4GDCA
Computer refuses to boot with both chips installed 4 GB.
Computer will boot and recognize 3 GB..( Apple 1 GB + 2 GB GEIL)
Both Geil Chips will boot, when paired with the Apple 1 GB chip.
machine recognizes 3 GB ram.
Please advise...

Ensure the computer's RAM is fully seated down, and then try resetting the PRAM by holding down options-command-P-R at boot. The computer will make the boot chimes and then reset and chime again. When it chimes the second time release the keys and let the thing boot normally. Hopefully that will let it recognize the RAM.

Can the iMac G5 take advantage of CAS2 or 2.5 RAM?

Can the iMac G5 take advantage of CAS2 or 2.5 RAM? I know it comes with CAS3 RAM.
THANKS

rob_ART:
i I've run some tests on a Power Mac with mixed results. In most recent tests, I saw an 8% advantage running the RAM preview render in Motion 2 with CAS 2 memory vs CAS 3.
It's possible to to it any number of ways. Some memory controllers will dumb it down and select one conservative CL value timing and stick with it. Others could bump it up.
It's unlikely to be that critical. A .5 cycle advantage wouldn't be that noticeable to most people, but some gamers insist on extracting every last bit of performance from their memory.

I seem to have inherited a lot of issues from previous macs i've had over the years resulting in my present iMac (21" 2.9Ghz i5) behaving strangely! Its slow on start up, and safari settings seem to reconfigure themselves ?? Any idea's ??

iMac 2.9Ghz intel i5
8GB
21.5"
Data migrated from a macbook pro and previously from an older iMac.
Can I restore to a clean start-up and re-install apps (docs, photo's music etc)from time machine without
bringing the issues that are causing a few issues.
ie Some web sites will not open ( I have checked that the sites are live).
Slow start up.
Some web sites ask me to check cookies- I've not changed them, and the problem is not constant ? (Safari is main browser).
Any advice gratefully received.
Tony

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed: Copy a line of text from this web page into the window of another application. Wait for the script to run. It usually takes a few minutes. Then paste the results, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Cursor freezes on 17" iMac G5 1.9Ghz

The Cursor keeps freezing on an iMac G5 1.9 Ghz...all the software is updated....

Hi strings, and welcome to the discussions.
But can you give us any more information?
What are you doing when it happens? What software
are you usually using? Do you have an Apple keyboard
and mouse? When did it first start happening? Does it
"unfreeze" eventually? How much RAM do you have in
your computer? What other devices do you have
connected to the computer, etc etc
The more information you can provide about the
situation the easier it will be to help you. On the
basis of what you have told us so far the problem
could be caused by any of a hundred and one things.
Cheers
Rod
Hello Rod: thanks for getting back to me.
I could be doing anything, It happens When i'm just moving the mouse across the screen to open a folder, or down to the dock to open an app.It can happen during start up,.or after the machine is on for more then 2 hrs. On that machine I am up to date on all SW updates, Including iTunes and Quicktime,..
It is connected to an Apple wired Kybd and Mouse, and the only external Drive is a 250mb Zip.
there is an NAS attached, and shared with two other macs(an intel mini and a G4 eMac). I have run Every Untility i could think of, and do not have this problem on the Mini with the same OS installed, or on theeMac with Panther running....and this JUST began happening tuesday night at 9pm. Thanks in advance for any assistance...

IMac PowerPC G5 10.4.7 1.8ghz 1GB RAM keeps freezing

I hope someone my be able to give me some advice.
I went from an old black powerbook G3 bronze that I had had for years and had the usual motherboard issues toward the end of its life to an Imac G5 PowerPC, which I was very lucky to get some help with as I am a disabled student. Unfortunately, this meant that I was not allowed to buy it direct from apple and get applecare, and had to have it from a preferred supplier (in March 2005) with their own "support" - they are not mac specialists by any stretch of the imagination! The imac has always had a habit of freezing regularly, the drive would suddenly start spinning really loudly, the cpu would shoot up to 100% and the whole system would freeze. This happens whether I am running Word, Excel, Safari, iPhoto, iTunes, Mail, iCal or Addressbook. The support guy said it was nothing out of the ordinary and I just accepted that at the time, but a friend of mine recently came round to give me some mac tips and had the system freeze on him 3 times in an hour - he felt it was some kind of error made when the software was originally loaded by the preferred supplier, but the iMac is now out of their 12 month guarantee.
We ran disc utility from the installation disc to verify and repair the hard drive and erased the partition that had been installed on the hard drive by the supplier (pre-loaded with the software, so they didn't have to do too much when their disabled clients screwed up their computers, one of the support guys told me), did a full erase of the hard drive and then a clean install using the original discs that came with the computer, but still have the same problem.
Can anyone please offer some advice on what the issue might be?
Thanks!

Christopher Mayled-
I am glad that you found the advice helpful. I had the same problem with my iMac and it *****. However, you did get your computer repaired and that is the bottom line.
We have three Dell laptops in the house, all covered by the infamous battery recall. Nobody from Dell has bothered to contact us yet. We have received no information in the mail. All three laptops were properly registered. I found out about the recall through the press.
I once had a stroller recalled by Toys R Us. I found out abput it by walking into a TRU and seeing the flyer hanging up on the bulletin board.
My guess is that if some of the recalled units fall through the cracks and do not get repaired then the company doing the recall saves some money. It isn't right but apparently it is what happens. Probably because of sheer numbers more than anything this happens but how do I know?

How will Logic Pro X run with a 2006 iMac (Intel Core 2 Duo, 2.16 GHz, 4GB ram)?

I have a 2006 iMac 2.16 GHz, 4GB ram, Intel Core 2 Duo. I am not planning on using plug-ins, I am a beginning artist and Logic Pro seems to have more than what I need. Any help would be greatly appreciated.

Yes it will.. I would recommend you use the combination of Snow Leopard 10.6.8 and LPv9.1.5 (or 9.1.8 if you have to..) with that particular hardware to get the best performance out of it... I would not recommend running any OS X version higher than 10.6.8 as each new version of OS X from then onwards.. placed a bigger performance hit on the hardware... and frankly, less stability with LP9.
As to how well it will run on that hardware.. will more depend on the sort of loads you place on it.. depending on the type and content of the music you wish to compose... It will run and you should be able to create reasonable sized projects.. but again, it all depends on the plugins used.. the number of them... the number of tracks and so on... so to give a more precise answer is difficult.

I upgraded to Yosemite and computer running very slow. It is an older iMac 2009. Thinking of downgrading os or upgrading ram unless there is something else I can try?

could the launch agents failing slow the computer or they just don't work. I mean I am willing to upgrade ram but not if there is good chance it won't change speed much. Also to downgrade is it necessary to format the hard drive?

IMac 8,1 2.66Ghz Core 2 Duo maximum ram upgrade possible

I have an iMac 8,1 2.66 Ghz Core Duo, right now I have 2Gb Ram, and I am going to upgrade it. Some forums suggest that it is possible to install a 2GB and a 4GB slot to get 6Gb, and some others says it is better leave it up to 4Gb. Can someone tell me if I should go for 6 or 4GB, I obviously prefere going for 6. Thanks

6 GBs is the max.
Correct and reliable Mac RAM can be purchased from online Mac RAM sources Crucial memory or OWC (macsales.com).
Here's the 6 GB RAM kit from OWC (macsales.com)

Will a new iMac 27 inch Quad i7 with only 4 gig RAM and 1 terabyte HD

Will this stock computer i7 Quad with the stock RAM and HD run Final Cut Studio 3 full suite effectively for basic HD editing from my new Canon hard drive/SD camcorder or should I immediately upgrade to 8 Gig RAM and 2 Terabytes HD to get the full benefit of this computer. I would like to upgrade them both later but I want 100% performance. I'm only editing 20 to 60 minute segments right now and only a few at a time and only one open at any given time.

I'm being told that "never" load your workflow into the same hard drive as your operating system. I'm sure that's an exact and professional statement and true, when possible. With this iMac you can't run and external hard drive and download effectively at the same time in order to bypass your internal hard drive because you have only one Firewire connection.USB 2 is supposed to pause and interrupts the flow so it is said to be ineffective for this purpose. I haven't found out yet about the SD card to an external hard drive but if it does I'm still being told that color correction cannot be added because it's in your external hard drive and the only solution is two hard drives in your computer to be able to effectively do all this and that is not an option with this current version of iMac..

I'm thinking about purchasing a 21.5" iMac. The base model comes with 8GB of RAM, and the RAM is not user-upgradeable down the road. Is 8GB enough memory or should I upgrade to 16GB?

I'm thinking about getting a 21.5" iMac which comes with 8GB of RAM. Unfortunately, the RAM is not user-upgradeable. Do you think 8GB is enough memory, or should I upgrade to 16GB? Besides internet surfing and email, I like to play flash games and listen to internet radio. Occasionally, I might want to stream a movie. I would greatly appreciate any advice you could give me.

For what you list, 8GB should be adequate. I ran with 4GB without any issue for over a year in my iMac i7 before I added RAM, primarily for running Win 7 via Bootcamp.
The tasks that need a lot of RAM are typically video editing/production, heavy-duty photo manipulation (not iPhoto or PS Elements), and professional page layout like Adobe Creative Suite. If you think that, down the road, you may want to delve into those fileds with this computer, by all means get the extra RAM.
I like to play flash games
I didn't try a lot of Flash games while I still had 4GB RAM but those I tried ran without issue and without causing a non-trivial number of page-outs

Why i can't run fcpx on iMac 3.06 Ghz core 2 duo with 16Gb ram?

I Can't run FCPX on my iMac.
It's working in theory, but it's stopping playback even without any effect, (video frames were dropped during playback - message), i can't preview any effect, as loading preview taking for ever.
I recently upgrade RAM from 4Gb to 16Gb 1067 Mhz DDr3, and I thought that's make a difference but not.
I have latest Lion 10.8.1 update. FCPX ver 10.0.5.
I try to work on 1080 video files located on main HDD , not external. they are from digital camera, 1920 x 1080, 1080p and codecs H264 linear PCM, 29.97 fps stereo.
Any suggestion?

You have loads of power so something is not OK.
Is your internal HD more than 80% full?
For a start trash your preferences using http://www.digitalrebellion.com/prefman/
Incidentally if you are using 50p/60p footage, that could be the problem especially on an internal HD.
You should always transcode 50p/60p AVCHD to ProRes 422.
Do that and I am sure you will see an improvement.

Why is my iMac (2.8.GHz Intel Core i7 w/ 4GBs RAM) using so much RAM?

Right now I have only Firefox open with 4 tabs. Firefox only has 1 extension (1Password). No other application open or running (that I know of). My dock has 17 icons (including basics like trash, finder, launch, etc). As mentioned I have a:
2.8 GHz
Intel Core i7
4 GBs RAM
21.5 Inch
Running on 10.7.3 (Lion)
My RAM situation is this:
1.83 GB Free
78 MB Inactive
1.40 GB Active
697 MB Wired
2.17 GB Used
4.0 GB Total
Image of my Activity Monitor (with user removed) here:
columns as follows: PID, Process Name, % CPU, Threads, Real Mem, Kind
I'm trying to figure out why my iMac is using so much RAM when I only have Firefox open? are any of these activities unnecessary and if so how might I turn them off and so they don't start automatically when I initially turn on the computer? This imac is two weeks old and so I haven't done a whole lot of customization yet. Please help if you can. Really appreciate it. Trying to optimize this baby. Thank you!!

Here's mine: I have 16 Safari tabs open, some with Flash junk, and 13 apps "open" according to the Dock indicator:
By the way the number of icons in your Dock has essentially no effect on memory. Only running apps - the ones with the little dot indicator - might be occupying memory. Even that is somewhat of an oversimplification, since "active" apps may or may not have any active processes associated with them. It's all a function of how Lion manages its memory resources, and that is a whole new world to most of us.
With Lion, Apple is seeking to eliminate the system effects of whether an app is even open or not. Just another trivial detail the average user ought not to be concerned with, in their opinion.
If you want a cursory introduction to that fascinating subject, Google the Ars Technica Lion review that was written a few months ago. It may ease your concerns about memory management. If you are an experienced computer user, it will rock your world.
