Apple shipped <a href=\"https:\/\/en.wikipedia.org\/wiki\/Mac_68k_emulator\">a rather amazing emulator<\/a> in the transition from Motorola 680x0 chips to PowerPC in the 1990s, and again in the 2000s with the PowerPC to Intel transition (<a href=\"https:\/\/en.wikipedia.org\/wiki\/Rosetta_%28software%29\">Rosetta<\/a>). There are seemingly no rumors one way or the other regarding emulation for the Intel-to-ARM transition. If I had to bet right now, I&rsquo;d say no, there will be no x86 emulation on ARM Macs&#x2009;&mdash;&#x2009;and that factors into why Apple is pre-announcing this transition months ahead of releasing hardware.<\/p>\n<p>[&#8230;]<\/p>\n<p>What happens with <a href=\"https:\/\/www.macworld.co.uk\/feature\/mac-software\/best-virtual-machine-software-3671133\/\">virtualization software<\/a> like Parallels and VMware Fusion? The obvious answer is they emulate x86 or they go away. How will that perform? My understanding is that however good the performance of ARM chips is, the instruction set differences make it slow for ARM to emulate x86. This is no little thing&#x2009;&mdash;&#x2009;there are a lot of developers whose workflows depend on virtualization software.<\/p>\n<\/blockquote>\n\n<p>Months is not a long time considering how long the Intel transition took and that these days developers are still cleaning up after new versions of macOS six months after WWDC.<\/p>\n\n<p>See also:<\/p>\n\n<ul>\n<li><a href=\"https:\/\/twitter.com\/stevesi\/status\/1270465602570686464\">Steven Sinofsky<\/a> and <a href=\"https:\/\/twitter.com\/ridiculous_fish\/status\/1270510975771279360\">Peter Ammon<\/a><\/li>\n<li><a href=\"https:\/\/shapeof.com\/archives\/2020\/6\/educated_guesses_about_a_mac_transition_to_arm.html\">Gus Mueller<\/a> (<a href=\"https:\/\/twitter.com\/ccgus\/status\/1270823011138940929\">tweet<\/a>)<\/li>\n<li><a href=\"https:\/\/pxlnv.com\/linklog\/arm-mac-transition\/\">Nick Heer<\/a><\/li>\n<li><a href=\"https:\/\/take.surf\/2020\/06\/09\/arm-wrestling\">Jesper<\/a><\/li>\n<li><a href=\"https:\/\/news.ycombinator.com\/item?id=23471095\">Hacker News<\/a><\/li>\n<\/ul>\n\n<p id=\"arm-macs-to-be-announced-at-wwdc-2020-update-2020-06-22\">Update (2020-06-22): See also:<\/p>\n<ul>\n<li><a href=\"https:\/\/eclecticlight.co\/2020\/06\/12\/what-would-an-arm-based-mac-mean-to-us\/\">Howard Oakley<\/a><\/li>\n<li><a href=\"https:\/\/bslabs.net\/2020\/06\/12\/reengine-not-reimagine\/\">Brendan Shanks<\/a><\/li>\n<li><a href=\"https:\/\/iam.fahrni.me\/2020\/06\/13\/arm-macs.html\">Rob Fahrni<\/a><\/li>\n<li><a href=\"https:\/\/news.ycombinator.com\/item?id=23504206\">Hacker News<\/a><\/li>\n<li><a href=\"http:\/\/codemines.blogspot.com\/2020\/06\/some-thoughts-on-macintosh-transition.html\">Mark Bessey<\/a><\/li>\n<li><a href=\"https:\/\/www.geekculture.com\/joyoftech\/joyarchives\/2715.html\">Joy of Tech<\/a><\/li>\n<li><a href=\"https:\/\/twitter.com\/jonst0kes\/status\/1271537011871100928\">Jon Stokes<\/a><\/li>\n<li><a href=\"https:\/\/tidbits.com\/2020\/06\/09\/the-case-for-arm-based-macs\/\">David Shayer<\/a><\/li>\n<li><a href=\"https:\/\/mondaynote.com\/osborning-the-mac-or-not-f0bbf4c319f0\">Jean-Louis Gass&eacute;e<\/a> (<a href=\"https:\/\/news.ycombinator.com\/item?id=23520920\">Hacker News<\/a>)<\/li>\n<li><a href=\"https:\/\/stratechery.com\/2020\/apple-arm-and-intel\/\">Ben Thompson<\/a><\/li>\n<li><a href=\"https:\/\/www.tomsguide.com\/opinion\/arm-macbook-reason-to-upgrade\">Jason Snell<\/a><\/li>\n<li><a href=\"https:\/\/brockerhoff.net\/blog\/2020\/06\/16\/yet-another-migration\/\">Rainer Brockerhoff<\/a><\/li>\n<li><a href=\"https:\/\/www.nytimes.com\/2020\/06\/19\/technology\/apple-intel-breakup.html\">Don Clark and Jack Nicas<\/a><\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>Mark Gurman (tweet, Hacker News, MacRumors, AppleInsider): The company is holding WWDC the week of June 22.
