dajkab Posted May 23, 2008 Share Posted May 23, 2008 Current Configuration Intel D945 GNTLKR Motherboard Intel Pentium D 950 Processor 2 GB Memory Saphire HD 2600 XT Video Card Dual UXGA LCD Monitors Logitech LX 300 Wireless Keyboard and Mouse USB 320GB IDE HD for OS X 5.2 LG Dual Layer DVD-RW Leo4All OSX 10.5.2 I have a question if anyone is encountering the same issue with the user interface using the OS X operating system. I've successfully got all of the above hardware working with both 10.4.8 and now 10.5.2. However, I've noticed a rather annoying issue when using either a keyboard for input or a mouse on the user interface. While typing the keyboard input seems to pause every 6-8 seconds and then buffers characters for a few seconds before displaying the characters that were typed. I've tried several settings to improve this but haven't had any success. I've also tried to use a standard 101 key PS/2 style keyboard to see if it was the wireless keyboard but had the same results. (Occurs in terminal, NeoOffice, Safari, Firefox, Thunderbird...) I also seem to notice that if I pass the mouse arrow cursor across the Launch pad on the screen that sometimes it will stop on an Icon for a few seconds similar to the duration that I have been seeing when typing. Works fine for about 6-8 seconds as I pass the cursor over the Launch pad and then just freezes for a couple seconds before allowing the mouse to move again. The mouse issue I can cope with but the keyboard entry is painfully annoying. I haven't used Macs for about 5 years but I'm sure this doesn't exist on the real thing so I must have something on my system that is causing this. Has anyone else seen this effect? Thanks in advance, DAJKAB Link to comment Share on other sites More sharing options...
c_c Posted May 24, 2008 Share Posted May 24, 2008 Hi, I have a compaq preaario F730US laptop. Its an AMD machine and I've always assumed that the problem is because of the decrypts required on AMD. But I have a similar problem. The keyboard buufers in the middle, the mouse is a bit jittery and the sound sttuters. In fact - sometimes the entire gui sttuters unless I keep moving the mouse. I found a diff with the kernel flags idlehalt=0 and cpus=2. Maybe that can help. Link to comment Share on other sites More sharing options...

I tried the recommended kernel flags but there didn't seem to be any change in the user interface. The keyboard input still pauses while typing and buffers input for a second or two every seven or eight seconds. Video display has been very good on my system very quick and much sharper than I've seen using XP Pro. Link to comment Share on other sites More sharing options...
zikade Posted May 24, 2008 Share Posted May 24, 2008 Try for a change booting using the -legacy flag. If it boots at all with that one - YMMV Or with cpus=0. I know, I know, but trust me on this one - it won't destroy your CPU at all.. Try different AppleSMBIOS.kext and/or AppleACPI.kext - it might be a PS/2-related thing, since you computer does have PS/2 ports. Link to comment Share on other sites More sharing options...
