PowerPC :: Fast User Switching Destroyed My Ibook G4?
Jan 26, 2007
I was switching between accounts. When I switched to my admin account, the computer went to the original welcome to your new mac set up video with all the welcome words in different languages, then started with the new mac set up stuff, ie, what's your name, etc. I tried apple Q but that didn't work, so I restarted the computer with control, apple, start. Now my computer just shows the white screen with apple and the round spinning circle.

I'm using a 2.33 GHz MacBook Pro running the latest version of SL. I periodically like to step away from my desk, so I'll click on my name in my Mac's menu bar to initialize 'fast user-switching', so that no one could use my computer without entering a password (similar to "lock" in Windows XP+). When I log back in however, I find that the desktop background that I had set was automatically changed to the default SL background. Could any of ya'll provide an explanation as to why this happens?

Ever since "upgrading" to 10.5.4 yesterday, fast user switching has been having problems. Randomly, when I change to another account (all are password protected), it will just instantly log me out, without even trying to close apps etc. - it literally takes it a second to log out, then I have to go back in and log in from scratch.

I have a quick question on how "Fast User Switching" is implemented in OS X. I have added an account in OS X yesterday for my wife, and I have enabled fast user switching.Now, what I wonder:- Do my downloads continue when my wife switches to her account? Example: Transmission (bittorrent), will it continue with uploading/downloading when my wife switched to her account?
- Do my applications continue to run when my wife switches to her account? Example: Handbrake (converting a movie). Will it continue with converting while my wife switched to her account?

When I'm logged in as root I notice the fast user switching menu doesn't display the short or full name, just a blank space. In my regular account, it does. Is this normal?

I used FUS years ago, but I can't get it to work now. I clicked Login Options in the Accounts preferences pane, and checked Use Fast User Switching. But when I log off any user, it closes all the applications and actually logs out. And when I switch back to any user, it loads all the apps from scratch and starts them up again. And when I log out as user X and log in as user Y, if I execute who, I see indeed that user X is not logged in

After upgrading to Yosemite, I had very serious problems with fast user switching. I do software development using my BackBook Pro, I need to switch between different accounts for testing/debugging purposes.
As long as I use fast switching, I will eventually have a system hang when logging out, login or shutting down. I either got blank screens, or dead login screen. In the end, I had to press the power button for 3 seconds to do a brute cold power off.

I have given away my old iBook (10.4) and my girlfriend would like a mail program. Is it true i can't just copy from my Macbook as MAIL runs on 10.5? What would be a good (free) alternative? and she has a Hotmail acct. Is it do-able with that? What's the keyboard shortcut to change the keybaord from English to Thai on my MacBook she has been switching on the iBook with the CAP LOCK key but not sure how she did it and nor is she?

When the MBPs came out with the dual graphics cards, people believed that they would be able to fast-switch between then. However, this is not the case; a logout-login is required to switch between the 9400M and 9600M GT on the MBPs. It was thought with the release of Snow Leopard this would be fixed.
So, has it been? will it be? Any word on using both graphics cards at the same time to boost performance?

I was watching WWDC 2003(panther intro) this morning, and I only just learned about Fast Account Switching from it. So, right after watching, I went to system preferences and enabled fast switching. However, right after I did this, my iMac made an unusually loud whir, which I assumed was the hard drive loading some files, although I have never heard it do this before. After about a minute of hearing this, I assumed that something was wrong, and I quit all applications other than system preferences, and when it didn't stop, I disabled Fast Switch. The iMac quickly quieted down. After thinking about it, I realized that I only had 1GB of RAM in the machine, which may cause the system to use virtual memory. Would having 2GB or even 4GB make this not happen, or would I need more than that? I never have noticed the iMac lagging in other areas, but would RAM help in general tasks too?

I have two users on my mac mini running OS X 10.7.4, both are administrators. When I click on my username in the upper right hand corner of the screen and select the second user, I can type in the password and "rotate" on over to the other user. However, from the second user account when I try and go back to the first user via the same process, no prompt appears when clicking on the user name from the drop down in the top right of the screen.

Mac mini (Mid 2011), Mac OS X (10.7.3)

I have a G3 iBook and just the other day the display stopped working. There were no signs of the display going bad, it's just went. Am I able to boot the iBook via Target Disk Mode on my PowerBook and run the iBook Hardware Test CD on it? Also, can I reboot my PowerBook and choose the iBook as the startup volume?
I know how to do Target Disk Mode but the latter I'm not sure about.

My brother's iBook G4 (800Mhz, First Rev) has completely splattered itself and we're getting a new Macbook for him under insurance. My iBook G3 (White, 900Mhz G3..the last G3 Rev of the iBook) has a failing hard drive.
Now, could I swap out those two drives, at least to recover stuff? And is there a specific method of opening up the iBook G4 so that I don't break stuff (I've already messed with my G3..and ended up with a dozen extra screws ^_^
Mainly the aim is to salvage the hard drive and swap them out; replacing my faulty iBook G3 one with the iBook G4 one which is perfectly fine.

I have a dual 2.5ghz PM G5 that works fine except that the heat exchanger leaked. Everything else is fine. My question is, I found someone on CL who was selling a quad G5 system for $375 because of a damaged mainboard. Could I take the Mobo from the dual G5 and put it in the case for the quad? The processor sockets are same but I'm unsure as to mounting issues.

I am looking at a Powermac G4 Dual 450 MHz with 1 GB of RAM and gigabit ethernet. I plan on using it for a file sever that 5 computer will use. It will be steaming video to the computers, sharing docs, and most importantly it will be used as the aperture library.It needs to be fast enough to do this or the whole app will run slow. If I finished maxing out the RAM and added a SATA card will it be enough?

I just picked up a G4 MDD off ebay. Everything seems to be working fine, and it passed tech tools tests for whatever that is worth. The only thing I noticed is that for about 2 or 3 seconds during boot the fans seem to rev up pretty high, then settle back to normal. Does anyone else with this computer have this issue or has anyone heard of it?

The fans on my G5 Pro are running at close to 3000rpm most of the time. I have read other forums and do not think this is normal at all. I started looking into the fans because I am getting frequent kernel panics (black screen crashes) and thought it might be the machine over heating. My CPUs are at about 50C to 52C and the fans are constantly running that fast.

Does anyone know what may be up with my Mac G5?? It just keeps on turning itself off without warning! It can happen at anytime... usually about 5 mins after I switch it on, although this has varied!

I have a G5 2.7ghz powermac. Recently it began switching itself off at start up. If it did boot up - it would only last for a few minutes that it would freeze.
I clean out the dust from the inside and even took the cpu cover off - none of it has made any difference. I have also replaced the lithium battery. Has anybody else experience this?

I have a 12" Powerbook 1 ghz (yes, it's getting old) running Tiger. When it's turned off, it charges just fine. However, when the computer is on, the power from the adapter keeps cycling on and off. For example, the lighted band around the power adapter tip switches from orange to off (NOT to green) repeatedly: about 3-4 seconds with power (lighted band is orange, screen backlight is bright, and if I'm in the Energy Saver section of the System Preferences, it thinks it's plugged in) and about 1 second with no power (lighted band is off, screen backlight dims, and if I'm in Energy Saver area, the computer thinks it's on battery power.
This is irritating because 1) the computer won't charge when on, and 2) as I type this, the screen goes from bright to dim to bright to dim etc.
Obvious answer is the power adapter, but I don't have access to another. What does everyone think? is it the adapter or some other problem?
FWIW, the internal hard drive just died and I'm booting from an external FireWire drive. It started doing this power thing a few days before the internal hard drive died.

My iBook G4 power supply failed and I'm awaiting a replacement. In the mean time, can I use the power supply from my iBook G3 with the iBook G4?

Right now I have a G3 iBook (900 MHz, 640 MB RAM, Combodrive, 40 GB HDD). I'm looking at a G4 iBook (1.2 GHz, 768 MB RAM, Superdrive, 60 GB HDD).
How much faster would the G4 be over my G3. I figure that after selling my G3, the G4 would only be another $200ish on top of it. Would this be worth it?

I just bought a parts ibook from ebay, but I managed to fix it, except there was no hard drive. I currently have a 6 GB HD in it with OS X.3.9 on it, but I want tiger. I have the tiger family pack, so I have a license for it. It only has a CD-ROM drive, so I am wondering if I can buy a 40 GB HD, and clone the one from my G4 onto it.

currently has 6 GB HD

I got a white iMac G5 about a year ago. Everything has been working fine until recently when I started to notice that its REALLY SLOW. What I mean by this is that whenever I try to open an application, load my widgets or basically do anything, it is really slow and Im seeing A LOT of beach balls. Just as i started typing in the title for this tread, it gave me a beachball. This computer is not that old so it should still be running smoothly.
Does anyone know why this is happening?
btw: I have 1GB of RAM, but it still operate really slow when I only have a few application open.

I have a PowerBook 12" on Tiger, 10.4.11. It is having occurrences of waking despite the closed cover. The cycles of wake/sleep are sometimes quite fast (seconds). I fear thrashing the HD. Here are excerpts from system log, followed by console log. The latter shows repeated instances of: AlsPB12 /usr/sbin/AppleFileServer: AppleFileServer ResetATalkService race detected. Which seems to implicate ATalk - is that AppleTalk? What relevance does AppleTalk have in today's systems?

Thought the house power had gone off because when I returned home, my Mac was off. Rebooted checked email, and went to get breakfast. Came back fan running very fast, and machine is locked and no video. Turned off by holding in power button. Same thing happens when I left again. I have now been on the machine for over an hour and no problems. What is causing this?

Is there anyway to fix this other than buying a new graphics card? I've searched but couldn't find a solution. The 7800GT in my G5 always spins at top speed and is so much louder than the whole system. I've had it disconnected for a while but I don't want it burning up . Thinking I just might wire it to the 5v side of the molex connector on the optical drive?
