Version 9.0.1 out, problem solved :-)
Last week I proudly released version 9.0 of iCaching with a whole new look, fitting in macOS Big Sur and native support for the new M1 Apple silicon Macs.
Unfortunately, the new search item on the toolbar appeared to crash on machines that are not upgraded to macOS Big Sur yet, even though Apple promised that this search item is backwards compatible.
So I stopped the roll-out of version 9.0 (only 10% of you received that update yet) and submitted version 9.0.1 in which I reverted to the old search item.
Version 9.0.1 is now available with a fix for this problem. Sorry for the inconvenience
