The new builds of iSR don-t support 10.4 anymore. This is an older build with the latest security certificate that opens sb2 files on 10.4. I will not fix feature bugs in this build any longer, just keep the security certificate up to date for as long as possible so it opens the files, and if I have more time work on the main build.
iSerial Reader 2.0.10 and Serial Seeker 1.3.6 (B2), are included.
Thanks to all contributors!
