The editor now has a navigation bar above its contents - we call it Breadcrumbs. It shows the current location and allows you to quickly navigate between symbols and files. To start using breadcrumbs, enable it with the View Show Breadcrumbs command or via the breadcrumbs.enabled setting.

  1. For standard Mac Java installations and so you don't have to continually update the setting when you install new Java VMs, set the -vm flag to simply /usr/bin: -vm /usr/bin If you want to use another JDK (that has the macOS directory layout, like the.tar.gz from AdoptOpenJDK) you should use.
  2. To download the latest nightly build of the installer, pick one of Windows 64 Bit, Mac OS 64 Bit (dmg), Mac OS 64 Bit (tar.gz), Linux 64 Bit. To download the latest nightly build of the installer with an embedded JRE, pick one of Windows 64 Bit, Mac OS 64 Bit (dmg), Mac OS 64 Bit (tar.gz), Linux 64 Bit.

The Mac is dead…long live the Mac!

Last week marked two major shifts in Apple’s personal computing platform: the introduction of Macs built around Apple’s own custom silicon, and the launch of Big Sur, the latest update to the venerable macOS operating system.

And of course, while we want to enjoy the here and now of these latest changes—and, probably, carp a little bit about the things that we don’t like—it’s also worth it to look at the path forward from here: the reverse trail of breadcrumbs laid out and leading, not back to where we came from, but on to the future.

Take the A14 to the M1

Apple’s claims about the performance of its debut Mac processor, the M1, have been met with equal parts amazement and skepticism. As is hardly surprising for a company as versed in marketing as Apple, the graphs and figures promised blockbuster improvements on not only the company’s earlier Macs, but also curves that outstrip much of the PC market. (After all, why make the change if it’s not significant?)

Those claims will be put to the test soon enough, and though I’m relatively confident that Apple isn’t going to brag about improvements that it can’t back up, there will certainly be places where the new Macs do better than others.

That said, even early numbers have pointed to these being jaw-dropping speed increases, of the kind that only come along once in a while. And it’s worth thinking about where the Mac goes from here: as my colleague Jason Snell pointed out, this is just the first chip in a whole family, and Apple’s only targeted its lower-end consumer Macs so far.

One advantage to those of us in the prognostication business is that the Mac’s roadmap is a little more predictable now. We’ve seen the kinds of improvements the company makes year after year to the iPhone and the iPad, the constant iteration of its processors, the gains it makes year over year in performance, graphics, machine learning, and so on. The Mac has hopped on that same treadmill, no longer bound to a third party’s schedule, and with results like those, there’s a reason it’s never getting off.

Go Big Sur or go home

In the nineteen years since Apple launched Mac OS X—more than half the platform’s life. now—the company has issued more than a dozen major software releases. Sometimes they’ve been hugely significant, other times they’ve felt more modest. But, in many ways, Big Sur seems like the most important update since that initial Aqua interface arrived to replace the classic Mac OS.

Design is a big part of that, because it’s something that Apple spends a lot of time on. There have been refinements of the macOS interface over the last two decades years, but it’s often felt more gradual. This time around, Apple seems determined to make everything old new again—perhaps indiscriminately, at times.

But this too is patently Apple. The company has always enforced a top-down approach to the look, feel, and behavior of its operating system, and its users, for the most part, trust the company to make good decisions. Sometimes missteps happen, and they get reeled back, and that too is likely to happen with Big Sur, though don’t expect the big changes to get reversed: this is Apple charting the course for its personal computing operating system for the foreseeable future. No, the Mac and iOS are still not destined to become one and the same, but the company is clearly looking to make them feel even more strongly related than they already do: not just from the same clan, but from the same immediate family.

Theseus statement

At this point, the Mac is like the fabled ship of Theseus. Slowly upgraded over the last 36 years, seeing replacements in processor architectures, underlying software, and pretty much every other component, it’s somehow both instantly recognizable as the same device that appeared on a stage with Steve Jobs in 1984…and yet also completely different.

And that speaks to a larger point of the Mac: it’s not just a product, it’s an ideal. In the same way that every new iPhone seems like it gets closer to some platonic concept of “the smartphone,” the progression of the Mac shows it approaching that fundamental core of what personal computing means. It might seem like the company should have made even more progress as the Mac nears the 40-year mark, but this curve is asymptotic, and I doubt that anyone at the company will ever conclude that the current version is perfect and can never be improved.

This is just what Phil Schiller meant when he said, more than half a decade ago now, that “The Mac keeps going forever.” Come whatever processor architecture, whichever form factors, and any software underpinning that may, the Mac’s work is never done, its watch never ended. The Mac you knew may be gone, but there’s always another just like it around the corner.

Goals

  • Pass all appropriate certification tests for Java SE 7
  • Include a complete, native Cocoa-based UI Toolkit
    • DONE.
  • Provide excellent performance
  • Integrate into main-line OpenJDK 8
    • DONE. OS X is now 'just another platform' in OpenJDK 8

Minimum requirements to run

  • An Intel Mac
  • RAM: 2GB

Note that only Mac OS X 10.7.3 and higher will be an Oracle-supported platform. It should continue to run on 10.6.8+ but that is not guaranteed. As of 1-Jan-2012 there are no plans to introduce 10.7-only APIs into the codebase.

Prerequisites to build

  • Hardware: Any 64-bit capable Intel Mac
    • RAM: 4GB
  • Minimum OS version: Mac OS X 10.7.3 Lion
  • Mercurial: http://mercurial.berkwood.com/
  • X11
    • On OS X 10.8 Mountain Lion: XQuartz
    • On OS X 10.7 Lion: Run /Applications/Utilities/X11.app to install as an additional download
