Disabling SIPįortunately turning off SIP is easier than it looks. Locks rarely stopped an expert burglar (he’ll just go through a window). SIP is just putting another lock on the door. Any malware clever enough to deploy on OS X will find a way to do so even with SIP turned on. Apple OS X users got by for fifteen years without SIP so it’s not as big a deal as it sounds. Apple and third party sites will try to scare you off of turning off SIP.

To be able to install any files at all to the System folder, first you must disable System Integrity Protection. Through OS X 10.10 that was all a user had to do to install a working AHT and then press D when restarting his or her Mac.īut since OS X 10.11 El Capitan, it’s not that easy. Installing AHT should be as easy as just as just copying the. Happily some enterprising Apple fans have collected all the versions of AHT out there for all kinds of Apple computers including Powermac, Powerbook, iBook, iMac, MacMini, MacPro, MacBook and MacBooks Pro.Īs we have mainly MacPros here from 4,1 generation, mostly upgraded to 5,1 firmware, we generally prefer the bundle which includes both 4,1 and 5,1 MacPros.
Unfortunately, recent versions of the OS have not included AHT or at least not for older computers. Normally you find AHT at this path /System/Library/CoreServices/.diagnostics There’s no joy in suffering through crashes which are hardware related, trying to debug your OS (software).

Apple has some lovely software called Apple Hardware Test a.k.a. This is easier said than done on older hardware. The first thing you should do is test your hardware. Start by Testing Your Hardware: Apple Hardware Test I’ll take you through the steps of a successful deployment of a 4,1 Silver Tower with High Sierra. What’s especially wonderful is that both of them will still run the latest Apple OS and software perfectly, with just a bit of preparation. In terms of cost for performance, no current Mac whether iMac or iMac Pro can touch the 4,1 and 5,1 Silver Towers. For video editors, the Mac Pro Silver Tower is one of the best computers ever built. Certainly they are more expandable, repairable and upgradeable than any other Mac built since, with SATA SSD and PCI cards and graphic card upgrades readily available and easily installed.
Even the eight core 2.26 GHz version is incredibly powerful and fast, outrunning any MacBook Pro and most iMacs, as will a hexacore 3.33 GHz or 3.46 GHz.
The Mac Silver Tower 4,1 and 5,1 remain one of the most powerful Macs ever made, depending on your processor.
