Apple has announced that 32-bit apps have a limited future on the Mac: They'll be fully supported in this fall's High Sierra release; macOS' 2018 release ("Really High Sierra") will "aggressively warn" users about 32-bit apps, and I would assume, they won't work at all in the 2019 version of macOS ("That Was My Skull!").
But how do you know which apps on your Mac are 32-bit and which are 64-bit? MacObserver has an article that discusses the easy way, via the System Information app—just look in the Software > Applications section, and you'll be able to see a list of apps and a 64-bit Yes/No column. But seeing the list is all you can do—you can't easily save the list for future reference, for instance, nor can you copy/paste the info to another app.
So here's a geekier solution to generate a list of your 32-bit apps, saved into a text file for easy future reference. Open Terminal, and paste this command:
This does the same thing as the System Information app, but it dumps the data in text form; the greater-than sign redirects the output to a text file named non64bit.txt, saved to your desktop. The grep is used to show only the 32-bit applications (the full line reads 64-Bit (Intel): No), and the -B and -A options are added to capture the lines before and after that line in the output.
This is probably not overly useful to most people, but I wanted a way to capture the list of apps, as I have over 290 32-bit apps on my machine, and it takes a while to run the System Information report each time.
Everything in that shot came via Amazon, except for the CPU heatsink/fan at the back right. That required more driving around than I'd care to admit (one business gone, one out of stock, another unexpectedly closed for the day), but I finally found something I liked. And with that, I had everything I needed to build the machine.
Note:This page contains an updated list (with links) of the parts I'm using in the project.
Now that I had the parts, it was time to try to turn them into a computer…
Back then, I built and used one, then wrote about the machine for Macworld, and they even lab tested it, where it held its own against real Macs costing much more.
Fast forward to 2017, and I've decided to tackle the project again. Why? Oddly, because there is a new Mac Pro coming, but it's a ways away. I want something I can use in the interim, without spending a huge amount of money on. When the new Mac Pro ships—assuming it's not an enhanced trash can design—I plan on upgrading, and the homebuilt Mac will become a gaming PC.
As I'm not writing about the project for Macworld this time around, I'm going to document things here on the blog as I go along. In today's installment, I cover the first steps in the process: online resources and parts decisions.
Note that I am not in any of the target markets for a typical Mac Pro buyer—I don't crunch huge scientific data sets, I don't render massive 4K movies, and I'm not compiling huge programs on a daily basis. But I have always been a fan of the Mac Pro for one reason (up until the most recent one, at least): Customization. Having a customizable Mac means it can last longer, as you can make changes to keep up with technology. I have owned both the Motorola and Intel era Mac Pros, and they were truly excellent machines.
One Mac to rule them all
The older Mac Pro (and its predecessors) were—as I recently wrote—wonderful machines, because you, the user, could do so much to them. You could add RAM, of course, but you can do that to most any current Mac.
You could also choose up to four hard drives to put inside the case—no messy cables, no need to worry about a child or pet disconnecting your drive while it's rendering a movie, etc. If you outgrew them, you could easily replace them. In my Mac Pro, I had an internal Time Machine drive (in addition to the external Time Machine drive.)
I use VMware Fusion often—I have virtual machines that span Mac OS X 10.6 to macOS 10.12.4 beta. I use the more-recent of these for supporting our customers on older versions of the OS, and keep the really old versions just for nostalgia purposes. (I have a bunch of non-macOS virtual machines, too, but they're not relevant to this tidbit.)
In all the time I've been using Fusion on my retina Macs, though, I've never enabled this setting…
…well, I enabled it once, but turned it off, because the end result was too small to see: In Retina mode, every pixel is an actual pixel, not a doubled pixel. On my 27" iMac, that meant the macOS VM thought it was running at (for example) 2560x1600 instead of a retina resolution of 1280x800. VMware even warns you of this in their Knowledge Base:
Mac OS X running in a virtual machine is limited to an approximate resolution of 2560 x 1600, and treats the display as a standard DPI device. This makes the text and icons to appear small in the OS X interface.
However, today I stumbled across this solution from Patrick Bougie—and it's brilliant in its simplicity. Patrick's post has all the details; I'll reproduce them here in abbreviated form, just in case his page ever vanishes.
The nice thing about the reinstall is that it's nothing like a reinstall from days of yore—you're not starting from scratch, so you won't have to reinstall everything when done. Apple makes this clear on the support page:
You can install macOS over the same version or earlier version, without removing your data. You don’t need to remove or disable the existing system first.
I say this with crossed fingers, but it seems that this reinstallation has potentially solved my Bluetooth issues. For the last two days, I've used my Bluetooth headphones without any static issues at all. In addition, none of my Bluetooth devices have disconnected. There is one comment from slajax on the original article that states this didn't work for them:
I’ve been having the same issue but with the gen 1 track pad and keyboard. I reinstalled the OS, PRAM etc replaced them with the gen 2 key board and track pad and also had the apple store replace the bluetooth antenna but still having the same issue.
If you've reached the breaking point with your macOS Sierra/Bluetooth issues, it might be worth the 30 minutes or so a reinstall takes. But please, if you go this route, make sure you have a good backup first, just in case. And if it works for you, please post in the comments (either here or on the original post), so that others might see, too. I promise to do the same if my now-working Bluetooth turns out to again be not-working Bluetooth.
When you relaunch Safari, you'll have a (really long) Debug menu on the far right of Safari's menus. And just why might you want a Debug menu in Safari? Kirk McElhearn offers up one good reason:
Auto-play videos suck. They use bandwidth, and their annoying sounds get in the way when you’re listening to music and open a web page. …
But you can stop auto-play videos from playing on a Mac. If you use Chrome or Firefox, it’s pretty simple, and the plugins below work both on macOS and Windows; if you use Safari, it’s a bit more complex, but it’s not that hard.
In Safari, they key is the Debug menu, as Kirk points out. Go to Media Flags and select (activate) Disallow Inline Video, and that should be the end of auto-playing video. See Kirk's blog post for ways to do the same in Firefox and Chrome.
Beyond auto-play video, though, there's lots to geek out about in the Debug menu…
I capture a lot of screenshots—both for this blog, and for our Many Tricks' help files and web pages. Depending on the project, I may need a full screen, a portion of a screen, a window, an object, or some combination of the above. As such, I use a few different ways of capturing screenshots.
First up are the built-in macOS screenshot tools, which you'll find on the Keyboard System Preferences panel, in the Shortcuts tab:
These four commands let you capture full screens or windows, directly to files or to the clipboard. And, for many users, these may be all you need. If that's you, great! (You may want to assign some easier-to-type shortcuts, as these—especially the clipboard variants—require some advanced finger gymnastics.)
I use some of these built-in tools, along with a key third-party app, to handle all my image capture needs.
While working yesterday, I noticed that my inbox was empty. Generally, I strive to keep it that way, but I knew it wasn't true just then—my phone showed six messages in my inbox. Even stranger, using a Smart Mailbox in Mail, set to "show messages in inbox for Many Tricks," revealed the six messages. It was only when clicking into the mailbox itself that I couldn't see anything. At first, I blamed Mail…
Mail has now decided my inbox is empty. That's not true—Smart Mailbox for inbox shows six messages. Quit, rebuild, no help. Sigh. pic.twitter.com/NVtQnGjjPV
When I looked a bit closer, I spotted a clue that maybe it wasn't all Mail's fault. The "(0 filtered messages)" as seen in my tweet normally reads "(0 messages)." This was different, so I went looking in Mail's menus for "filter," where I discovered View > Disable Message Filter. Because the menu read "Disable," that meant the feature was enabled. I selected it, the menu switched to Enable Message Filter, and bingo, my inbox messages were back!
So what happened, and why wasn't it more obvious to me what had happened? The fault lies both with me and with Mail.
[Note:Glenn F wrote about this very issue for Macworld a few months back…sorry I missed it, as it would've saved some investigative work on my end!]
One of the most-useful tools in macOS is also one of the most useless: The Services menu. In theory (and occasionally actually true), the Services menu lets you quickly take action on something—a selected file or folder, or a chunk of text. In reality, the Services menu is a vaste wasteland of unused functionality, and a place where pre-assigned keyboard shortcuts go to hide from your attempts to use them elsewhere.
If you install a fair number of apps on your Mac, you may be surprised by the amount of stuff in your Services menu. Here's a look at my iMac, after I reset the Services panel (System Preferences → Keyboard → Shortcuts → Services) to its defaults:
If you're good at counting, you spotted 123 separate services flowing past. Not all are active, of course—"only" 58 are. Of those 58, you'll see some subset based on whatever you've selected…but even that subset can present itself as a huge list:
That's really not very helpful when you want to quickly apply some action to your selection. To make the Services menu useful again—and to potentially free up some keyboard shortcuts—you'll need to actively manage your Services.
