#635 Unable to adjust maximum memory in AppStore version due to application signing.

[Ryan Fosnaugh]

Running App Store version 5.1.1 on Mac OSX El Capitan and running out of memory slowing down 3d rendering. I've tried to edit the Info.plist file as described in the FAQ, however doing so breaks the applicaiton signing and the application won't launch with the file altered. Any other way to increase usable memory?

The security system required by Apple for Mac App Store applications forbids to alter their Info.plist file, so I do'nt think you can increase the max memory used by this version.
I could increase the max memory in the next version to 3 or 4 GB, but fear it could cause problems on computers with little RAM. I could also remove -Xmx parameter in which case, the program will use 1/4 of RAM at maximum. What do you think?

[Ryan Fosnaugh]

1/4 of RAM as maximum sounds appropriate and would help for my 16 GB laptop
but not impact my 8 GB one which is OK as the system typically takes around
4GB any ways.

To get around for the time being - I'm using the downloadable version to
render video where I run into RAM issue and the app store version to add
new furniture and textures.

From version 5.4.2, it's possible to adjust the memory size of the Mac App Store version with the -Xmx Java option.
Please, edit the SweetHome3D.cfg file found in the sub folder Contents/Java/SweetHome3D.cfg of the Sweet Home 3D.app and add the -Xmx option in the line after [JVMUserOptions], for example -Xmx6g for 6 GB max memory.
