If your Mac is operating at a slow pace, then for that reason alone it is worth the upgrade to OS X 10.6 Snow Leopard. keka supports compression to 7z, Zip, Tar, Gzip and Bzip2 and it can extract from RAR.
#KEKA FOR MAC OSX 10.6.8 FOR MAC OS#
Ive update the installer/the automatic update doesnt have this issue. Keka latest version: Free mutliformat compressor for Mac OS X. Faster Installation Time: Installing Snow Leopard on multiple machines takes approx 15 minutes in comparison to around an hour for Leopard. Mac OS X said maybe that waterfox wasnt compatible with 10.6.
