If you've got a 1980's Macintosh (such as the Macintosh II) with more than 8MB of RAM, make sure to install Mode32 as all models from the 1980's (68K) came with a 24-bit addressing ROM, which can only reach up to 8,388,608 bytes (8MB) and nothing higher than that.  All Macs starting from 1993 came with a 32-bit clean ROM which pushed the RAM addressing limit so high (4GB) that most Mac models could not even physically reach it...

A mac user said : While setting up a PowerBook G4 (17" 1.33Ghz) to boot into Mac OS 9 natively, there is the lack of controlling the fans. Mac OS 9 is terrible at monitoring hardware temperatures, and especially with unsupported machines. There is no software that runs under Mac OS 9 that can control system fan speeds. G4FanControl is an excellent tool for PPC machines running Mac OS X, but may not work with all machines. After...

Many iBook G4 laptops (and possibly other models) have a problem with the inbuilt AirPort card failing, and then causing regular kernel panics. This can be avoided in Leopard, and possibly Tiger, by replacing the kexts responsible for the AirPort 1. As soon as you turn the computer on quickly turn off AirPort in the menu bar. 2. Open TextEdit and save two blank files to the desktop. Name the First one  IO80211Family.kext.rtf and...

[WIP, coming soon] Hi.  Altough this guide has nothing to do with retro Mac technology per se, it could still prove to be useful to you, wheter you use an old Mac or a new one or even Windows.  It has nothing to do with what brand of computer you use, what type of storage media you use or even how old the storage media is.  DATA recovery applies to everyone and failing hard drives, especially new ones, are often caused solely...

Instead of being continually frustrated with SheepShaver, although an amazing piece of emulation software, I decided to resurrect my old PowerMac 7300. The problems I had were that the CMOS battery was dead, and the hard drive was tiny, only 6GB. The battery was replaced with one from Amazon for about $8.00  I had a stack of older hard drives, luckily one that was IDE and 120GB in size. Under OS 9, the OS needs to be installed in the...
