MagiCal 1.1r2 memory leak

  • Type: Crash
  • Version Tested: 1.1r2 (Intel)
  • OS Version Affected: Mac OS X 10.6
  • Status: Open


Dear Charcoal Design,

I am sad to report a serious problem with MagiCal 1.1r2 and Mac OS 10.6.2. (I cannot comment about OS 10.6.0 or 10.6.1.) MagiCal has been a trusted part of my Mac experience for several years. I am sorry to have to remove it, but here's the reason why I must do so...

I noticed my two Intel Mac Minis developed inability to return to sleep normally. I also noticed the "Info" button (i) in the lower right corner of MagiCal's calendar did not activate the drop down menu. That reminded me of problems with MagiCal under Leopard OS a couple of years ago.

When I looked in my Console log on both Mac Minis I saw numerous warnings for Magical stating, "*** __NSAutoreleaseNoPool(): Object 0xc064df90 of class NSImage autoreleased with no pool in place -- just leaking." Six such Console warnings were reported every second.

Activity Monitor told me that Magical was using over 1% of my CPU cycles on both Mac Minis. Quitting and relaunching Magical eliminated the Console log messages temporarily and CPU usage dropped back down to 0.4% for a while. However RAM usage gradually climbed upward at 1/10th of a MB every few second, then Console warnings resumed and CPU usage gradually climbed back above 1%.

Removing MagiCal from my Mac Minis eliminated the Console warnings, and it returned both computers to normal sleep functionality.

I will be happy to volunteer myself as a Magical beta tester on my Intel Minis (10.6.2) and my PowerBook G4 (OS 10.5.8) if you would like.

Thank you so much for giving the Mac community years of wonderful software. I have no expectations regarding free or low cost software, but I feel our great software developers deserve constructive feedback when a serious problem manifests.

I am experiencing similar behavior with MagiCal 1.1r4 running on Lion. There must be a memory leak.

I am also experiencing a serious memory leak with MagiCal 1.1r4 running on Lion. It hasn't crashed or caused other things to crash, but I've got 8GB of RAM and I stop it before it takes it all. The first time I noticed the excessive memory usage it had climbed over 2GB.

Memory leak still bad in version 1.1r4 under 10.9

Four years after first reported, have to assume Magical is not being maintained any more so am uninstalling it

Still causing a problem (same 1.1r4) on an old Mini (short on memory) running 10.11.2. Sad because it's one of the few that I can get to put up the date my way. Symptom: after running for a few days of iTunes the free available memory reported by iPulse drops from 1.2G to .8 and Magical goes up from .3% CPU to over 7. Quitting and restarting MagiCal frees up most of it.
