While sandboxing adds another layer of security for Macs, not even the App Store nor sandboxed apps are 100% safe, as highlighted by the attack on the Chinese version of the App Store by the XCodeGhost Virus.

XProtect defends Macs against various types of malware, by scanning downloaded files for signs of infection, but it needs to be regularly updated to recognize new or emerging threats - and it won’t help you if you unwittingly land on an infected or unsafe website.Ī digital certificate is always seen as proof of a file’s security and a surefire sign that the file contains no malicious code, but cybercriminals can still plant malicious code at the file completion stage, exploit security gaps to sign their malicious files with valid digital certificates, and more.

For instance, if you have a "MacMini 2,1" then your system will run Lion. If it says something else then as long as your model number is above those in the table then you should be good to go. If your Mac's model number matches one in the table then you will not be able to run Lion however, if your Mac is not in the table then check the second line of the command output to see if it says "x86_64." If the second line says "x86_64" then you will be able to run OS X 10.7 Lion. This Mac has all the processor capabilities needed to run OS X 10.7 Lion

This should be all that's needed to determine if your Mac will run Lion however, if you need further verification that your computer will work, then you can open the Terminal application (in the /Applications/Utilities/ folder) and follow these steps:Ĭopy and paste the following command to the Terminal, and press Enter:Ĭheck the first line of the output, and see if it matches anything in the following table (models that will not run Lion): If it has both "Core" and "Duo" in the name, then there is a number "2" between those two words (ie, "Core 2 Duo" and not "Core Duo"). Due to a planned power outage on Friday, 1/14, between 8am-1pm PST, some services may be impacted. Operating Systems Mac OS X 10.11, Mac OS X 10.9, Mac OS X 10.10, Mac OS X 10.8, Mac OS X 10.7, Macintosh, macOSX (deprecated). It says "Intel" or "Core" somewhere in the name, and does not have "Solo" in its name
A quick way to see whether or not your Mac has the appropriate processor is to select "About this Mac" from the Apple menu and look at the "Processor" section, and then see if the following criteria are met: This Mac will not run OS X Lion because it does not have an Intel processor.ĭespite some 2006 Macs not being able to run Lion, others from that year have the capability to run it just fine, with the difference being that the deficient Macs were built with the 32-bit Intel "Core Duo" processors instead of the 64-bit capable "Core 2 Duo," "Xeon," or "Core i3/i5/i7" processors.

Unfortunately, this means that some of the early Intel-based Macs will not be able to run Lion when it is released, so if you did purchase one of the first Intel Macs in 2006 (or purchased one second-hand) then you may not be able to install and run OS X 10.7. Apple's newest release of OS X is just around the corner, and part of its advancements is that it will not only be Intel-only as was the case with Snow Leopard, but it will also run exclusively in 64-bit mode and therefore require a 64-bit CPU.
