Hi. When I bought my Macbook (late 2006 model, 2.0 Ghz) I just needed 17 seconds from the moment I pushed the power button until the moment it was ready to work, with desktop and finder ready. Now it takes more than one minute! It's true that, at the time, I had Tiger running on it, now it has Snow Leopard. But it is also true that I upgraded memory: from the included 1 GB to the 2,5 GB RAM that it has now. It surely became faster when I upgraded the memory (I notice that specially on opening applications and finder windows). But on startup it takes too much time; it takes a lot of time with the Apple logo and the spinning wheel thing (after the logo and the spinning wheel disappear, it's quite fast). Even when opening applications it's still too slow. Opening Firefox for the first time after starting up, for instance, takes almost 40 secs. While my wife's Macbook, with less RAM (2 GB) and a processor just slightly faster (2,16 Ghz) takes only 11 secs! Even my old (although upgraded) Power Mac Sawtooth (running 10.5.8) is must faster on startup. I ran Onyx and - guess what - it became worse... Any ideas?
