OS X :: Fast GPU Switching In SL?
Aug 14, 2009
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'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

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.

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.
Info:
MacBook Pro

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?

Can the Mac mini with 4GB of RAM run VMFusion 2.02 with Windows XP Home properly without any problems? Is 2.0GHz fast enough, or even 2.26GHz fast enough for VMFusion? Does the Mac mini have enough horse power to run Windows XP?

I have a Time Capsule as my main router with a 802.11n (b/g compatible) network, with an Airport Express (802.11g) extending it. I have AT&T Elite DSL ("up to 6 Mbps") and according to both 2wire.com and speedtest.net, I'm getting somewhere in the neighborhood of 5.1 Mbps. When I hook my DSL directly into my computer via ethernet, I get the same results. I ran a few "real world" tests and found that the results I got were pretty accurate. I downloaded a 4.8 MB file in about 7 seconds and a 17.8 MB file in about 30 seconds. So my question is...at what speed does wireless n come into play? I'm getting close to the highest speed AT&T offers on a network that is, for all intents and purposes, a g network.

I'll be switching from a PC to a MAc, and it just dawned on me that there are a number of cookies on my computer which I would like to take with me. I find some cookies to be very valuable. Some sites, I want to remember me; such as, banking and some shopping sites. Also forums and other places which have passwords and can remember me, or can remember where I've been on the site. Is there anyway to take those along? My procedure is to copy everything I need to my external drive and then copying from there to the Mac. I don't think I'll have much of a problem finding out where things should be put; so, I'm not using any automatic migration assistance or plugging the two computers together.

I currently have a 1.5TB external hard drive ive been using with my PC, (approx 90% full) which i believe is in NTFS format.
I have heard rumours i may have to re-format this to Fat32 in order for it to function correctly with my Mac.
Is this correct? can anyone shed some light on the situation?

did the way that you switch through open windows change in SL? usually I hit ` to switch through windows and shift ` to go backwards through the list. Now it seems though the window order isn't being followed correctly. Lets say i have 5 open windows starting at 1 hitting ` takes me to window 2 then 3 then 4 then 5 then 1. typing shift ` would take me to 5 then 4 then 3 then 2 then back to 1. Now though, under SL it seems not to follow that very simple design rather if I start at one and page through to say 3 then start again it jumps back to 1 then to 2 then to 3 and then finally to 4.

I have little to no knowledge of the compatibility of the Macmini to a PC. I currently own a 4 yr old HP Pavilion. There's not much wrong with it, it's slowed a little, but my husband and I have been wanting a Mac. We saw the Mac mini and like what we see, but we don't want to have to buy a new printer and monitor when both work perfectly. The monitor is an HP vs15 and the printer is a HP Photosmart USB. Will these work if we buy the Mac mini?

My logic board broke on my 07 mbp and i decided to buy a new 15" i7 anti glare 7200rpm. My question is how should i go about getting my files onto my new computer. I have a time machine backup, will it let me just install that onto my new computer? If so, do I want to do this or will that cause problems since its a different machine.

So for awhile I was following all of the to do about the GPU switching. Eventually I figured I would just deal with it and check back a month or so down the road. So since I've been out of the loop I was wondering if anybody can update me?
I've been using gfxcardstatus and it is very useful but would love to apple to just give us an update.

Am I the only one, or does the SSD fill up faster than a standard HD? Right now I of course keep my iTunes library on an external drive, and soon I will do the same for my iPhoto library as well. That said, it seems that I loose space faster than I would expect, is that how these drives behave? All I can say is thank goodness I got the 256 GB model!

Using Firefox but it annoys me in the bookmark management and freezing up too often. Safari is faster but no way to help the toolbar color for visually impaired. Is there another good, fast browser available?
