G5 fan issues with Leopard

I've had my G5 for many years, and despite the many complaints by others about unusual fan activity, I've not had one issue until I installed Leopard. Now, for the first time, the fan is changing speed frequently (every few minutes). It is not like a jet taking off, but it gasps every once in a while. Is this an improvement with Leopard, something I can adjust, or is there a problem with Leopard?

Hi Jack
Have you tried [resetting the SMU|http://support.apple.com/kb/HT1436]?
Not sure if resetting the PRAM/NVRAM is relevant. I have seen posts that that can help when the fans are problematic but from what I've read at Apple Support there seems to be little stored in there which controls the fans (for instance [here|http://support.apple.com/kb/HT1379?viewlocale=en_US] and [here|http://support.apple.com/kb/HT1242]). But I guess it never hurts to try.
You can also try one of several fan control utilities out there, such as [smcFanControl2|http://homepage.mac.com/holtmann/eidac/software/smcfancontrol2/ index.html].

Graphic Issues with Leopard - iMac 24" White GeForce 7300 GT

Upon installing Leopard, I've noticed several graphics issues and general lag and delayed response with the interface. I'm running a 24" iMac 2.16ghz White early 2007, 3gb of RAM, with the GeForce 7300GT card. I have Time Machine disabled, and Spotlight has fully indexed.
When installing Leopard, I did an "Erase and Install" and have manually installed my Applications after the Leopard install. I'm using only a few applications that are all "Leopard ready" and have a relatively clean system at this point. I have also cleaned the PRAM, per the recommendations in some of the threads ive read, which didn't seem to correct the issue in this case.
It seems that any time I run any type of video or graphical application, such as Photo Booth, World of Warcraft, iChat, etc, I get a large amount of lag and slow response with the interface. Windows respond very slowly, and the applications freeze for 15-20 seconds. Even when not engaging any applications, opening folders in the finder as well as the dock appear to stall and respond very slowly.
Aside from these issues, Leopard has performed very well and I have had no other issues. Quicklook and coverflow all seem to respond very quickly and smoothly. My guess is that it may be driver related as it seems to be centered around items that are engaging the video card, though it is strange how some graphical effects seem to work smoothly while others are rather choppy. I have been watching the Activity Monitor and there don't appear to be any processes that are sucking up CPU, and nothing obvious that may be reducing performance.
I'm just curious if anyone else has noticed anything similar to this on similar hardware, or possibly may know what the culprit could be. My best guess, again, is that it could be the drivers or firmware with this specific hardware that I'm using.
Thanks for your time

I've had the same graphics issues with my white iMac 24 (serial no starts W8638), but with the GeForce 7600 card. AppleCare got me to do all the usual stuff (reset PRAM, clean Leopard install etc) but problems continued. The usual pattern is that after a while horizontal lines appear (usually in Safari) and things deteriorate form then on until there is so much pixellation that I have to turn off and back on.
Yesterday I ran for several hours using SMCFanControl to set the fans to max and had no problems, so my suspicion is that the additional graphics requirements of Leopard are over-heating the graphics card or logic board.
The Apple engineer took the machine away today and said they'll probably replace the logic board and graphics card (I think they can't change one without the other in the iMac?).
Will be a few days but I'll report back on what repairs they make and whether they solve the problem. My fear is that any changes they make will have no effect if its a design problem and the card is just not up to the job without over-heating. Though it could be the card just needs a good clean
Has anyone else tried increasing fan speed?

Re: Graphic Issues with Leopard - iMac 24" White GeForce 7300 GT

I noticed the same issue. It's especially noticeable in Photo Booth. The video and sound don't sync up.

X200 Fan Issues with Windows 7

Hi all,
I've just done a fresh install of Windows 7 Ultimate 64-bit onto my X200, and everything works great except for 1 thing - the fan constantly runs and doesn't stop at all as long as the laptop is on.
I've seen a few other posts of other X200 owners facing the same issue, but with little resolution. I've unintalled Access Connection and turned off my Wireless LAN but to no avail - the fan just keeps on going.
I've switched back my old HDD with XP Pro, and the X200 is quiet with little fan movement - so it definitely seems to me to be Windows 7 and the X200.
Anyone here faced the same problem and managed to resolve this? It's definitely very irritating if you're mobile and constantly need to work with your laptop on your laps!
Solved!

Now I've gotta figure out if the HDD is typically like that or if I got a dud.
There have been quite a few comments about vibration issues with 500GB WD Scorpio Black drivers in numerous web forums. What size is your WD Scorpio drive?
I have a 320GB Hitachi 7200rpm drive in my X200 and it has no vibration problems.

Colour Management issue With Leopard and PS CS3

Hi Everyone,
Since I have installed Leopard I am having colour management issues with Photoshop CS3 and my Canon i9950 printer.
My screen is calibrated with a Spyder and I used to ask Photoshop (in 10.4.11) to manage colour when printing and used the Spyder profile. Everything came out as I saw it on screen.
Now in leopard when I do the same thing everything comes out too yellow on the print. If I ask Photoshop to let the printer manage the colour it is too red. If I use the default colour management (photoshop managing the colour and it choosing the colour space it is better, but still too yellow).
Photoshop gives the hint to turn off colour management in the printer but there is no option for this and it also said the same thing before of course (when it worked in 10.4.11).
Any ideas?
Thanks.

You need to use the correct printer profile for the paper you're using. If the printer didn't come with any pre-built profiles, check Canon's web site to see if they have any profiles available for your printer that you can download.
Printer profiles are very specific. You can't take take a profile for glossy Epson paper and expect it to work very well for Canon glossy paper.

I'm having exactly the same problem, only my printer is a Canon Pixma iX4000. The colour is all bleached out, it looks exactly like when you've accidentally printed an RGB file on a CMYK printer, and at first I thought that was what I had done, but it isn't. This is very frustrating, I've spent all day going through the manuals, recalibrating etc, but no luck. This is a brand new Mac Pro and printer, but if its not going to print what I see on screen it's just expensive junk.
I wasn't sure if the problem was Leopard or the printer or CS3...

Big issues with Leopard and writing to NAS units or Windows servers

Quick run down of the issues
1st client has a number of G5's all running 10.5.2
NAS units running embedded Windows SBS 2003 or Windows Storage .
All shares have worked fine before the macs were upgraded to Leopard.
Now the macs can see the shares, mount and write to the folders. But immediately afterwards all inherited permissions are stripped from the folders/files and only the owner of the file/folder can access them. All other mac users have no access. It seems that Leopard is ignoring the inherited permissions of the share and just applying its own.
2nd Client
Number of imacs running 10.5.2. Can see the mac shares on the server running Windows SBS 2003 fine. The minute any files are copied you get the progress of the items being copied, seems to appear on the server and then just hangs.
In most circumstances the copying crashes the whole server.
Have tried binding the imacs to AD, but no joy. SMB sharing (with Appletalk turned off) dosent help either.
Somewhere there seems to be some gremlins with AFP and windows shares
Anyone have similar issues or bright ideas ?

Alright I'm running into the same issue with my iMac 10.5.2 connecting to windows server 2003 r2. I'm about to go nuts, I can log on to the server, open files manipulate them and sometimes I'm able to save that file back to server but I'm unable to transfer almost anything new to the server, (I can create new folders though). When you try to transfer something to the server I get "progress of the items being copied, seems to appear on the server"... then it hangs, a corrupt file is left on the server. If you try and open that file I get an error message on my mac, "OS X is currently using this file" on a pc it will say the file is corrupt. I'm forced to carry my psd files on a flash drive and walk to coworkers machines to upload it to the server... (haven't had time to set up parallels). I'm the only mac in the office and I'm seeing why I've been so spoiled at past jobs where its 100% macs.

HELP: Mail issues with Leopard

I have been having an issue with Mail since I upgraded to Leopard. I am getting the following message when I wake my Mac from sleep:
There may be a problem with the mail server or network. Check the settings for account “[email protected]” or try again. The server error encountered was: The server “mail.mac.com” cannot be contacted on port 143.
Does anyone know why this might be happening? Mail seems to work fine otherwise...

I had update problems with my PowerBook G4 as well. In my case the update stalled at Writing Package Receipt-it was installing 4 packages so I am not sure which one failed-but about this Mac showed 10.5.2 version-however the receipts were not anywhere -either in Software Updates/Installed Updates or in Library/Receipts/boms or in Console Logs-therefore, I concluded that the Update was only partial. I was unable to update it to completion using the independently downloaded Combo updates. So........., I restarted with the install DVD and did an Archive and Install (it reverted back to 10.5), then ran Software Update. It installed 7 items some of them relating to iTunes, iWork, iLife, QuickTime etc, including the combo 10.5.2 updater. It took an hour or two but everything finally installed. After that I ran Software Update again and it installed the Graphic Update. Now everything is fine except Permissions Verify/Repair takes quite long.

Disk Utilities/Permissions Issues with Leopard

What is wrong with Leopard's permissions? I have had numerous permissions issues, and had to reformat my two disk drives and Archive & Install Leopard on my startup disk after a Tiger to Leopard Upgrade.
Now when I run Disk Utilities and Repair Permissions (which I do routinely), what used to take a minute or two in Tiger now takes a half hour (or longer) in Leopard?
I ran Disk Utilities on my MacPro and it has taken nearly 25 minutes and is still going. My MacBook Pro is estimating the time at 1-minute remaining (where it started), and it has also been going for 25 minutes plus. I would like to go to bed, and don't want to leave my MBP running over night if I don't have to.
This is a major issue and one which Apple needs to address immediately. I trust I am not the only User having this issue, is this the case?

No your not the only one. It's been reported throughout the discussions. Appears that some of the errors reported in disk utility will not effect performance. Still, I expect that something is being observed and worked on as an update..

My visit to the Genius Bar regarding video issues with Leopard

Having video hang up issues with imove 08 and viewing videos on my webgallery. We opened a video on my web gallery on 3 computers with Leopard and two computers with Tiger at the Genius Bar. The Tiger machines allowed immediate playback where the Leopards took 3-5 minutes to view. Crazy!
Also noticing fickering with my footage in imovie 08 which I never had with Tiger. Plus when I delete a clip in my project, my workspace goes completely black and I must go into another project open it, then back to the first project and it reappears....Very frustrating.

DVD Drive is dead. Hopefully was the issue.
Thanks for all the input

3rd party app Installation issues with Leopard

I recently purchased a new MacBook Pro with Leopard installed. I have been trying to install (from original media) a number of applications (such as Office:mac 2004) that install and run well on my old G4 running Tiger. On Leopard the installer won't even open the package. I have checked permissions, am in an admin account, etc but nothing seems out of place. I also recognize that these installation packages are pre-Leopard but I can't imagine all my software is now obsolete. Anyone have any suggestions?
Thanks,
Doug

Yes I have checked selected applications that I am having issues with. Office:mac 2004 is being used by others on Leopard and Intel based platforms. Not sure if 100% of these users migrated the installation from a prior machine or were upgrading the OS so already had it installed but that is highly unlikely. A demo copy of this even came with my machine. Per advice from other discussion groups this was completely removed prior to trying to install my bought copy of the software. I had believed that Rosetta would allow most (all) apps that ran on a PowerPC under Tiger to work. Since I can't get the installer to even run, I can't tell if the app itself will work.
BTW, I am about to go back and reinstall Leopard to see if that solves the problem.

Network issues with Leopard fresh install

I have an iBook that I was running Leopard on with no issues yesterday. It is no longer my main computer, so I wanted to wipe everything and start from scratch with a fresh install of Leopard. The install went smoothly. I did an Erase & Install setup from a Leopard Upgrade disc (but already had Leopard on my system so upgrade verified OK). When I booted up for the first time, it appeared everything was working normally.
I went online, downloaded a couple pieces of software I frequently use, and then started to set things up. This is when I ran into issues. I could browse the web without a problem. I could set up email with POP access, but not IMAP. AIM with Adium connects just fine. Tweetie won't connect. Dropbox won't connect. It's like some ports are being blocked, but others aren't, and I can't figure out why.
I have tried/verified:
OSX firewall is off
Restarted router/cable several times
iBook is in router's DMZ- outside of router firewall
Repaired permissions
Reset PRAM
Anyone have any suggestions or other troubleshooting ideas?

Here are the steps to selling*:
http://www.macmaps.com/selling.html
Mac Pros that shipped with Leopard should install from the Mac Pro labelled discs. Those that came with pre-Leopard, you should still include the Mac Pro discs, though if you desire to install Leopard on them, you should also include the Leopard discs that are retail. Leopard retail looks like * and do not say Upgrade, DropIn, or OEM.

So I ran the test : stop my external drives connected to the FW Sonnet card, and there it was ! no more task in red... I know many of my friends had same issues with same G5 (2, 2.2 ,2.7) and especially, using video apps like final cut with FW cameras and external drives. I suspect de dual kext to be a part of the problem here, because on other Macs, nothing happens like this.
Can I hope for some help or can we expect driver update to get started at work with Leopard soon ?
Thx for answers

Thunderbird issues with Leopard

I'm using a Thunderbird 2.0.0.9 IMAP account with Leopard, but cannot access attachments larger than about 200K. When I try to do so, the opening or saving stops midway through, and then Thunderbird becomes inoperable, forcing me to restart the app.
Apple Mail works okay, but I'd rather not move everything to it if I can help it. BTW, POP 3 accounts don't work for me with either with Thunderbird or Apple Mail, but appear to work for those running Tiger in our office.
Anyone else experiencing similar issues, especially with Thunderbird IMAP and Leopard? Any ideas on how to address this?
Thanks!

For me also, Thunderbird just won't send mail, using Leopard. Asks for password twice despite using manager, and then advises unable to connect.
Had the same problem with MNail, however a Repair Permissions whilst booted from the install disk fixed Mail, not Thunderbird drat.

More Heat/Fan Issues with Tiger--Help

I have followed the heat & fan issues for sometime. However, I finally decided it was time to move from 10.3.9 to 10.4.3.
I upgraded yesterday, first using the upgrade option to move from 10.3.9 to 10.4.0 and then installed the 10.4.3 combo upgrade. I've repaired permissions and rebuilt the disk directory using Disk Warrior. There were no directory errors and only a couple of trivial permissions changes.
However, my Powerbook's fans are running constantly and my CPU heat is always pegged at about 135 degrees F, which is as hot as it ever gets. This happens within about 40 minutes of starting the Powerbook up cold and it stays that way for as long as I'm using it, regardless if there are any apps being used.
Activity Monitor indicates that the launchd process is using from 18% to 20% of my CPU, even with nothing else running. I've disabled all Spotlight indexing and I've turned Dashboard off. It appears that it's the lanchd process that is accounting for the extra heat and fan use. It simply won't drop below the 18% to 20% of CPU. There is no other process that is using any significant amount of my CPU when nothing else is running.
My processor is set at Automatic, the same as when I was using 10.3.9.
I was using Silk, Application Switching Menu (ASM) and Macaroni, but I've uninstalled them. No change.
I've reset the Power Manager (including deleting the com.Apple.PowerManagement.xml file) and reset NVRAM. Again, no change.
Finally, when I boot back into 10.3.9 (on my backup hard drive), the fan activity and heat return to what I consider normal--much lower than with 10.4.3. Specifically, the heat and fan activity is directly related to CPU use. If I'm not doing anything, the heat drops and all the fans go off.
There is one other curious effect of 10.4.3 vs. 10.3.9. When I'm running Firefox (latest version), all Firefox user-interface stuff (menu selections, opening many tabs in succession, etc.) are MUCH more sluggish than when using 10.3.9. Frankly, I was expecting the opposite.
I would really like some help with this. I've read all the troubleshooing info on MacFixit and Macintouch related to heat and fan issues associated with Tiger.
12 1.5Ghz Powerbook Mac OS X (10.3.9)

I'm the originator of this thread and I appear to have an answer.
I tried an "Archive and Install" of Tiger, on top of my existing 10.4.3 install that was giving me the trouble I described above. I had the time today and figured "what the heck[ll]".
I then installed each additional piece (10.4.3 combo update, airport updates, quicktime updates, java updates, etc), stopping after each one to check CPU temperatures and CPU use in Activity Monitor.
I'm now back to a full 10.4.3 install, with all current recommended Apple software and I don't have the heat/CPU use problems I previously had. There is no significant use of the CPU by the launchd process.
I also re-enabled Spotlight indexing and that doesn't cause a problem either.
Also, my entire system is *MUCH* quicker and responsive. I wish I knew what piece in my previous system install was causing the problem, but hopefully my experience can help someone else. When in doubt, do an "Achive and Install" rather than an update to the previous system installation.
By the way, with heavy Spotlight indexing going on and mild web browsing, my CPU temp is just 112 to 115 degrees F. Previously, with no Spotlight indexing and with NO apps running, my CPU temp was maxed at 135 degrees with fans on full. And if you're reading this thread, you know what max fans sound like on a 12" PB.
