[Macos-users] if your adobe reader freezes...
by Olya Igonkina 06 Nov '13

Hi all, This tip might be of interest for you : http://wccftech.com/turn-app-nap-specific-applications-os-mavericks/ Practically Maverick puts some applications to "sleep", when not used. For my laptop busy with Vidyo that resulted in Adobe Reader to be super slow, as by the time people on the meeting would get to next page, my pdf would freeze [==asleep] and it would take ages to turn a page. By then the speaker would naturally be few pages ahead - very annoying if you chair the meeting... After I have disabled this AppNap for AdobeReader, I did not have delays anymore [so far]. Also vidyo and cern webcast seem to take insane amount of CPU after upgrade..

[Macos-users] Mavericks and ROOT
by Jeroen Van Tilburg 06 Nov '13

Hi, For those of you that have not yet upgraded to Mavericks and occasionally develop code or run ROOT locally, you might consider waiting a bit before upgrading. For those that could not wait to get the new OS (like myself), below are some instructions to re-install ROOT. In case you find mistakes or misconceptions please correct them. o First, why to reinstall ROOT in Mavericks. When compiling something in ROOT you will probably encounter: "Undefined symbols for architecture x86_64" When this happens, this means you need to reinstall ROOT. o Prepare for re-installing ROOT from source after Mavericks update. You need to (re-)install the command-line tools for Xcode: xcode-select --install Then remove XQuartz and reinstall the latest version (download from web or App Store). You need to do this even if you already had the latest version *before* upgrading to OS X Mavericks. Visit: http://xquartz.macosforge.org/landing/ o Install ROOT from source. It seems that you need to get the latest ROOT patches, otherwise PyROOT will crash. git clone -b v5-34-00-patches http://root.cern.ch/git/root.git root-v5-34-00-patches cd root-v5-34-00-patches ./configure macosx64 --enable-roofit make -j6 source bin/thisroot.sh o In case you use PyROOT, you will notice that the X windows are not appearing. This is because PyROOT thinks it is running in batch. The workaround is to add at the start of your script, or in a .pythonrc file: import ROOT ROOT.gROOT.SetBatch(False) After that you can do things like from ROOT import * TBrowser() in your scripts. See https://sft.its.cern.ch/jira/browse/ROOT-5673 and http://root.cern.ch/phpBB3/viewtopic.php?f=14&t=17238 It took me 1.5 days to get this working. I hope this saves some of your time. Cheers Jeroen
