"Mavericks" Mac OS 9 support?

Mark

The following line of text in Apple's description caught my eye, and makes me wonder if there might be some external display issues with the new OS: "OS X Mavericks takes full advantage of every display connected to your Mac, giving you even more flexibility to work the way you want. There’s no longer a primary or secondary display — now each has its own menu bar, and the Dock is available on whichever screen you’re working on."

This can be turned off in system prefs > mission control > untick displays have separate spaces. main issue i'm seeing thats more important is the timer coalescing. which results in the cpu spiking to get its stuff done, meaning serato and ME get swamped with other bits going on, resulting in a choppy screen and sometimes audio stuttering. I have tried this line in terminal that i found online, to switch it off. set interrupt coalescing-time 0 seemed to work, however after a reboot started having the same issues. so don't know if this would need typing in every time ... (an effort) also read that this timer coalescing is only operational whilst on battery power.. i don't know how true this is

Thanks for the useful information PhilDJ. Seeing a lot of completely useless "I ran Serato for an hour and it was all good" on the Serato forums today, so it was a refreshing change to see some actual tech details. Anyway sounds like jumping on this OS right away for "professional" use isn't a very good idea. I'm sure Nick will have whatever issues affect ME all fixed up soon enough anyway :-)

Anyway sounds like jumping on this OS right away for "professional" use isn't a very good idea you mean it seemed it after a few bottles of beer... hmmmmm. sucks to be me i suppose. I'm speaking to Nick at the moment, hoping he has the answer

as for the serato for an hour comments. they're correct. my mates done a gig on mavericks this evening, also running Sdj this evening has been solid. open ME to show videos and it's spiking and stuttering, close ME again and it's back to being solid, So its more an issue to do with displays / processing video content.

Last night I tested for about 4 hours if not a bit more. SSL 2.5 / ME 2.2 / TTM 57SL / 2009 MacBook Pro 15". No crashes or weirdness so far. Running HDMI for the video output. Played with 57/SL effects and ME transitions/effects. Also surfed the internet with multiple tabs open. At one point I had Finder open, Quartz Composer open, Contacts open, Calendar open and Safari open all while SSL/ME was running and connected to the internet. Haven't tried Lemur or Serato Remote on my iPad yet. You can turn off the menu bar on multiple displays in the system preferences under Mission Control. You can also set specific apps (of your choice) to NOT use the new "App Nap" feature by going into your Applications folder, right click/get info and check "Prevent App Nap". Just in case you get uncomfortable with the idea.

and have you changed any of the settings apart from that?

I think I've cracked it. at least enough to make it workable for now. After studying the activity monitor, i noticed a kernel task that was going nuts, so googled it and came across this link http://www.rdoxenham.com/?p=259#more-259 it says that instead of individual tasks, they are all grouped together under one umbrella task. and for the sake of temp control, run small background bits keeping it away from main apps. and explains how to delete the profile for the MBP to stop this from happening. after doing this. the kernel task has been tiny, I've run Me and serato for an hour twice, with a reboot in-between and its ran flawlessly. the Cpu gauge in serato Dj still kicks off a bit. but activity monitor is running low. :D i think maybe Sdj is just reading one core??? Maybe not an ideal fix. but short term whilst another route is found :) Phil

Full gig last night from 10pm-2am. No issues running everything I said above. No audio glitches or video glitches: Mid-2009 15" MBP 2.66 / 8GB RAM / 320GB HDD / 3TB External HDD (FireWire 800) / SSL 2.5 / ME 2.2 / TTM 57SL / Technics 1200 MK5/ Serato Remote and Lemur running on iPad 4 and iPhone 4S connected USB and wirelessly Wonder if I should try this kernel issue just to see if it boosts some more speed or not

No philDJ, those are the only settings I messed with and changed
