![]() ![]() ![]() Last month, Google tripled the maximum bounty for bug reports from $5,000 to $15,000. Of the 42 vulnerabilities patched in Chrome 39, 12 qualified for bug bounties, which ranged from a high of $16,500 split four ways to a handful of $500 rewards paid to individual researchers. company continues to crank out 32-bit versions for PCs running Windows Vista or the already-retired Windows XP. But because that browser requires Windows 7 or later, the Mountain View, Calif. Google launched a 64-bit Chrome for Windows in August. A portion of those machines, however, will be capable of running Chrome, as they boast 64-bit CPUs, even though they're powered by out-of-date operating systems. Opera Software's Opera also comes in a 32-bit edition.Īccording to Internet metrics firm Net Applications, just under 13% of all Macs ran Snow Leopard, Leopard or an earlier OS last month. Mozilla's Firefox, for example, includes both 32- and 64-bit versions in each OS X edition's package. Owners of older Intel 32-bit Macs still running Snow Leopard - or even earlier versions, like 2007's Leopard or 2005's Tiger - will have to either risk running an unpatched Chrome 38 or switch to a different browser. OS X 10.6, aka Snow Leopard, which was released in August 2009, was the last edition to support 32-bit Intel Macs. The MacBook Air has always featured 64-bit processors. Apple stopped selling 32-bit iMacs in September 2006, and shifted to 64-bit for the Mac Mini in August 2007. That means Chrome users with older Intel-based Macs - those sold between January 2006 and August 2007, at the latest - will not be able to run the new browser.Īpple shifted its lines from 32- to 64-bit at different times: The MacBook Pro, for instance, went 64-bit in October 2006, while the less-expensive MacBook switched to 64-bit in November 2006. The first generations relied on 32-bit processors, but by August 2007, Apple had completed the transition to 64-bit. The appearance today of Chrome 64-bit also signaled the retirement of the 32-bit version on the Mac, which will be stuck on Chrome 38.Īpple's then-CEO Steve Jobs trumpeted the switch from the PowerPC line of processors to Intel CPUs in early 2005, and his company began selling Intel-based Macs in January 2006. Google has touted Chrome 64-bit on OS X as faster to launch and less of a memory glutton than the older 32-bit edition. "We're now bringing these benefits to OS X with Chrome 64-bit for Mac, version 39, due to be released in November," the company said in a brief blog update on Sept. But the next month Google revised the schedule. In August, Google announced that Chrome 38 would be the first in its series of 64-bit browsers on OS X. ![]()
