OSX Mavericks is available as a free download today. Does anyone know if zBrush is compatible with it? Don’t want to upgrade and have zBrush not work.
hey Jeycally, i was about to ask the same thing. I am with you on this!
Does anyone knows?
Come on people! 
just installed it and having problem with zbrush, wish I didn’t update…
I get a random very annoying lag when turning around the model.
I updated the wacom drivers to latest version didn’t change a thing, I guess graphic drivers are the cause (macbook 13 HD4000)
also have a macpro running a radeon 7950 but I guess I won’t give a try with this one
Thanks for the info Stephane_D. Think I’ll hold off for a little while before updating.
I guess its a wiser decision, the very slight updates are clearly not worth the risk.
to be more specific on the issue,
If I turn continuously around the model I get a 0.5 seconds lag every 3 seconds, when the model is displayed back you are lost, it is hardly usable.
Polycount doesn’t matter.
anyone having similar issues?
EDIT:just submited a ticket to pixologic support, It appears to be specific to zbrush, I have no issue with mudbox and maya.
Hey, you could try out the following:
- Open the Activity Monitor and Terminal (Standard OSX Tools).
- Look for the Process-ID (PID) of ZBrush.
- In the terminal window type in “sudo renice 20 ZBRUSH-PID” (without the ") and hit Enter. So when your ZBrush-Process-ID would be “330”, type in “sudo renice 20 330”. You have to enter your password after that and I think this command only works when you have set a password for your User-Account.
This command changes process priorities. -20 would be highest priority and 20 the lowest, as far as I know.
Hope that solves the pen-lagging-issue inside ZBrush for you
Thanks for the update! Do you think it could be and issue using a wacom with zBrush or does it happen with a mouse too?
I don’t have a mouse but I just tried with the macbook trackpad and it doesn’t lag at all, good news
Seems like wacom drivers are the issue after all so it should be fixed soon I hope,
latest version is just 2 weeks old its a shame the issue was not noticed during the beta
Yeah, report it to wacom, they should get right on it.
Good to know about the Wacom drivers. I use my wacom about 50% off the time with zBrush (work area too small) so I’m going to go ahead with the update. Fingers crossed.
It took 3 hours to download and install but got Maverick running. I’ve noticed apps load slower than before but read that it should improve as the computer is reindex. Once zBrush loads, its runs smooth like usually. I’ve noticed a big lag when hiding parts of your sculpt but is handling a 40 million poly sculpt pretty good.
hanks ralvar, sorry I missed your post
I am not trying this though as my laptop is really not meant to be used for zbrush much,
so I’d rather not mess with priority settings of the app as I am not sure what it will be taking priority on.
thanks for the help anyway 
to all of you, macbros out there
i’ve found kinda workaround to avoid stuttering when using wacom tablet in brush under mavericks(on a wacom forum)
while zb is opened, open terminal and type renice 20 $(pgrep ZBrush)
which would actually change the priority of zb process(you can change the number, 20 actually is enough)
voila, the stuttering is gone
p.s. i’ve actually made a simple script which you can simply 2click instead of going to terminal and typing/pasting each and every time

just run it after launching zb and you’re done
hope that was helpful. let me know if it works or not.
cheers
Hi Stephanie_D, I experienced the lag you are talking about. For me it only comes from working on the mac after waking it up from sleep mode. Try a proper restart and see if the lag disappears.

Wow this helped, saved my day Thank you!
This is great info, thanks guys
i’m not upgrading just yet. Other macs in my house are on mavericks, but these are not work machines, it works fine for internet, games and movies etc. My Mac Pro is staying on Mountain Lion until all the kinks have been ironed out. I don’t Neeed to upgrade. Although the multi-monitor setup sounds good and tabbed finder, but I am ok with second bar and the old method for the moment.
I tried setting priority to 20 on zb and it actually fixed a problem with fans ramping up even when I’m working a low res model (100k polygons). Is there a problem with the mac install of zb and the way it handles processes?
I’ve always had that problem with ZBrush and the MacBook Pros. Just got the 2.6 GHZ Retina and the fans area even more eager to go on. Happens in Modo and C4D too. What’s new is the machine does a very good job of keeping cool. I suppose I’d rather have fans running than a too-hot-laptop.
The set multithread to 1 and steps to 8 setting do help. Thanks for pointing that out. Wish I’d know about that a while back.
One problem I am having is installing GoZ. Failed on both Modo and C4D.
Update on the GoZ problem: Reinstalled GoZ from ZBrush/Troubleshooter/help folder fixed the problem
