The most important one is probably keeping unnecessary memory usage to an absolute minimum. You do need to keep some guardrails in place to help ensure that however.

All of this is why Apple went through the incredibly awkward and painful process of moving the entire Mac ecosystem to the preemptive multitasking UNIX-based system called OSX.ДЄctually, considering the fragility of the entire principle the old Mac OS is based on, it's kind of amazing that it does work as well as it does. In the old Mac OS, memory allocation was fixed (by the settings in the 'get Info' window) and it's easy to have an app simply run out of memory, thereby causing it to hang and therby causing the entire system to go belly-up.

Although it is now rarely used in larger systems except for specific applications, cooperative multitasking was once the only scheduling scheme employed by Microsoft Windows and Classic Mac OS to enable multiple applications to run simultaneously.ДЄs a cooperatively multitasked system relies on each process regularly giving up time to other processes on the system, one poorly designed program can consume all of the CPU time for itself, either by performing extensive calculations or by busy waiting both would cause the whole system to hang.ДЄlthough 'one poorly designed program consuming all of the CPU time for itself' is a common cause of 'freezes' it's not the only cause. This approach, which was eventually supported by many computer operating systems, is known today as cooperative multitasking. I've excerpted this from Wikipedia 'Cooperative Multitasking':Д®arly multitasking systems used applications that voluntarily ceded time to one another. I never liked thoseвЂ¦ turntable-tape deck-CD player-tuner combo stereos either. Please excuse my blabbering-on here if youвЂ™re already geared in this mannerвЂ¦ some may not be aware of this вЂњeliminate-the-variablesвЂќ approach. Here, trimmed down to the absolute bare necessities after many years, only the вЂњinternet portalвЂќ machine freezes, crashes or pukes around here anymore, thankfully. I use a much newer iMac for email & internet and вЂњsneaker-netвЂќ to move files for upload or download. Again, with no unnecessary or extraneous un-needed вЂњfatвЂќ. One for the raw sound files and вЂњpreliminary workвЂќ and a second Mac for additional вЂњpolishвЂќ (strings and other effects) before tweaks & final output or archivingвЂ¦ with back-ups written along the way as he progresses towards his finished piece. And all three are tied together over a LAN (each workstation has dual monitors for tool palettes, etc.).ДЄ friend of mine (DAW) operates in a similar fashion, only sharing between just two Macs. Another is for 3-D modeling & rendering (OS 9.2.2), while a third (OS 9.2.2 & 10.4.6) Mac is dedicated to Illustrator and the merging of images (and text) for final output.

One is a scan & Photoshop station (OS 8.6). The вЂњdivision of laborвЂќ вЂround here is placed on 3 different 'older' Macs. And I do mean completely stripped down except for their intended specific use. No internet, mail, music, games, etcetera on my graphics workstations. Maybe common knowledgeвЂ¦ or standard practice, but вЂњtrimming the fatвЂќ or вЂњparing downвЂќ what apps, CPs or extensions (that you donвЂ™t really need) is optimal for stability on any вЂњworkstationвЂќ regardless of OS version or itsвЂ™ intended duty.
