I recently bought my first Mac (specs in sig), and I'm a bit confused about RAM usages. I read some of the threads around here, and know about the difference between Free, Wired, Active, Inactive, and Used RAM. I also know that a Page Out is OSX sending a request to the HDD as opposed to the RAM due to a shortage. I haven't been able to upgrade to 2GB (or 4) of RAM from the standard 1GB just yet, and I don't plan on it for at least another few weeks. My question is, granted that, what is the expect number of Page Outs to be expect for running Safari, Adium, iTunes, and Simplify Media (application that allows you to share iTunes libraries with friends). I'm currently looking at 1.29GB worth of Page Ins, and 767.53MB of Page Outs for about 9 hours of uptime. Is this OK, or am I having memory leaks somewhere that I need to be concerned with? Edit: I'd also greatly appreciate it if someone could tell me what the "normal" temps for a 20" 2.0Ghz iMac would be. I bought it refurb'd (getting an MBP for college in June, figured I might as well get an iMac now so I wouldn't be completely new to OSX in college), so I'm a bit concerned. According to iStat Pro, the hottest part of it (the Airport Card) is at 65 degrees.
