If you need to install Mac Os X Leopard on your PowerPC that does not meet all the requirements, you can use this leopard assist tool to temporarily fool the system. You still need your own 10.5 Install Disc.

Download the tool here: LeopardAssist.app

Perhaps LeopardAssist looks a little basic on the surface. A few clicks of the mouse is all LeopardAssist needs to configure your machine for installation, from the processor to the drives – all without requiring any manual editing of files or burning of additional discs.

Extensively Tested.

LeopardAssist has several years of testing to its name, across most models and series of PowerPC Mac, and even today it continues to receive feedback and feature requests for consideration. In addition, developments and information gathered in the improvement of LeopardAssist have assisted in helping other Mac related projects on both PowerPC and Intel.

Widely Supported.

LeopardAssist is widely used and supported across many specialist Mac communities, such as the ThinkClassic Vintage Apple community ( thinkclassic.org ) and the MacRumors PowerPC Macs Forum ( forums.macrumors.com ). Any questions related to the use, care and maintenance of your PowerPC based Mac and the installation of OS X Leopard can be directed to one of these communities.

Use f.lux App to automatically dim your screen at night

Computer screens, tablets and mobile phones emit full spectrum light around the clock, just like the sun. Exposure to blue light at the wrong time of day can keep you awake later and interfere with the quality of your sleep. f.lux tries to help this by removing blue and green light to help you wind down in the evenings.

It can take a few days to get used to the new colors at night, so we recommend setting the night-time colors in f.lux to whatever feels good to your eyes. After a few days with f.lux, experiment with the settings to warm things up a little more and find which color works best for you. Our default setting of 3400K on Windows removes about 3/4 of the blue and about half of the green light.

Probably my favorite app for mac and windows. It’s a must have if you use your computer late at night.

Get f.lux.
