Dear MC's I have a late 2012 iMac with 1TB Fusion. Have Bootcamp Windows 7 and Mavericks running. Problem is that i switch a lot. Like 10 times a day. Every time I needs to hold the option/alt key. In the beginning it was fast, like the pictures popped out in 10 seconds after the startingsound. Nowadays it takes up to 1 minute! Probably because I have to many (and big) applications on both OS. I reinstalled everything (both OS) and still I get this problem. Although is not the end of the world, there must be a better solution. I used to work with ReFit. I read that this (and ReFind) didnt work in combination with the Fusion drive. Virtual OS will not work for me! Tried Parallel, VMware and the free VirtualBox but none is getting to my requirements. So is there any replacement for refit or refind?????? Or is a way to fix the booting time????
