If you have a solid OS X 10.11, 10.12 or 10.13 installation you will have a recovery partition which can be accessed as simply as pressing command-R while rebooting before the grey boot screen comes up. 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. What's your experience with updating? Positive, negative, or neutral? I'm posting this to provide feedback for those thinking about making the switch.The Mac Silver Tower 4,1 and 5,1 remain one of the most powerful Macs ever made, depending on your processor. Of course I haven't had time to do in depth testing, but from a cursory inspection, all my music making and DJ software seems fine and ready to be updated to the latest versions. Everything else seems to be working flawlessly. (Edit): Trim Enabler had to be turned on via the menu=> action, instead of the gui on the pop-up. Upgrades become available for the iWorks suite (Pages etc.), and there will be some security upgrades to install via the App Store. Some other stuff: the Photos app rescans your collections to be able to categorize them better. MenuMeters doesn't work post El Capitan, but there is a port if you want to go that route. Strangely, it showed up fine in Firefox? Eventually I got a pop up in my network filter asking me to authorize connections to the site's main servers and everything was ok after that. ![]() Safari couldn't reach my website after the update. for some reason the RoomWorks plugin included in Cubase wasn't loading properly in a project, but I need to check this further? there were lots of new processes from Apple that needed to be either blocked or authorized on Little Snitch (Spotlight tries to use location services via nsurlsessiond, etc). I had to do some tweaking on various settings in System Preferences to disable extra stuff I didn't want or need (certain settings in iCloud, Siri, etc.). The only 'glitches' for me thus far were very minor: It goes without saying that I made complete backups of my system and hard drives before upgrading. I've been using an older version of Maschine (2.5.6) as recommended for Mavericks users. Clearly the SSD make the installation process speedier. I was conscious that I'd have to upgrade sooner or later but kept procrastinating.įor starters, I should say that I'm on a late 2011 MacBook pro, 2,2 Ghz, 8 Gigs of ram and SSD (Samsung Evo) internal hard drive. I held off for a long time out of not knowing / not wanting to risk that it might break my current set up. I recently upgraded from Mavericks to Sierra and was pleasantly surprised at how relatively pain free the experience was.
