MacTF 1.1
A new version of MacTF has been released. This update contains mainly bugfixes and reliability improvements.

USB errors should now time out, and commands now check to see if the Toppy is responsive before they ask for anything. This means that even if there was an error somewhere that further commands should hopefully work without requiring a physical resetting of the USB by re-plugging.

And perhaps most importantly (for me at least!), the upload bug that caused some files to fail has hopefully been solved. I always suspected it was a file-size related error, but could never work out the pattern. Luckily peteru (the developer of the Linux command-line tool puppy) hit upon the same bug in the Topfield USB protocol/firmware. So now I am able to easily avoid the bug, and uploading seems to work great.
