Calibre 8.1.0/OSX 10.5.8
I love Calibre. It is perfect for managing book readers (Kindle 2 & DX, ipad 1 & 2) for our family.
I have a question regarding Calibre 8.1.0 running on a mid 2009 imac, with OSX 10.5.8. Recently it seems to be running very slow, does not always detect a device. It's work perfectly for such a long time that I did not notice immediately that the buttons at the top were not lined up properly ie. it's not displaying properly. I only have just over 100 books. Has this got something to do with the new devices? Should I upgrade to Snow Leopard or should I just go back to a previous version of Calibre?
Thank you for your help.
