See what I mean? I DO blame Apple for this, because they shouldn't be making major changes to the WindowServer and Metal frameworks IN A FREAKING POINT RELEASE.

These are the kind of changes you'd expect between 10.13.x and 10.14.x, not 10.13.3 to 10.13.4.

I wonder if they at least solved the issues with NVIDIA graphics. The OS is absolutely unusable with some kepler-based nvidia graphics (600 series) as it experiences corruption/pixellation.
 
People that take the position you’ve taken with refusing to update are INCREDIBLY foolish! You’re leaving yourself exposed to an ever growing amount of in-the-wild exploits that take advantage of issues in older OS versions, especially in this cyber climate. And please don’t tell me “I’m experienced enough to avoid sites and tasks that could compromise me”, because that is the apitome of arrogance and hubris.
And people like you who like to criticize without a single word that is helpful are INCREDIBLY annoying! Next time, tell me something I don't know, and keep your offensive and harassing comments to yourself.
 
El Capitan and Sierra are still supported by security updates so im not losing much by staying on sierra except a few emojis lol

Agreed! I’m on High Sierra. I’m just incredibly frustrated with Apple taking away features or compatibility, and slowing down our devices with updates.
 
Well, you can add ASUS USB-3 external displays to the list of thing 10.13.4 broke. The forums on ASUS are reporting it, and I live it by trying to upgrade my MacBookPro13,1 (13", 2016). LCD went absolutely haywire with flashing and switching desktops, and the external Asus MB169 Ezlink display wouldn't even work. Had to revert to 10.13.3
how did you revert to 10.13.3?
 



Users of popular Mac desktop extension app Duet Display are being advised not to update to macOS 10.13.4, due to "critical bugs" that prevent the software from communicating with connected iOS devices used as extra displays.

When installed on a Mac and an iPad (or iPhone) and the two devices are connected using a Lightning cable or 30-pin connector, Duet allows users to extend their macOS desktop space on the Retina display of the iOS device. However, unspecified changes in the latest update to macOS High Sierra, released by Apple yesterday, causes the Duet client app to hang, and users are being advised to hold back from upgrading, at least for now.

The critical issue was highlighted by Duet's ex-Apple developers in a blog post on the Duet support site, quoted from below.
Duet's developers are recommending that users contact Apple through the company's online bug reporting form to get the issue prioritized. In the meantime, the developers are "actively looking" into workarounds to reinstate Duet's functionality in macOS 10.13.4.

Duet Display is priced at $19.99 in the App Store, and unlocking the Pro features to turn the iPad Pro into a drawing tablet costs an additional $19.99 per year through an in-app subscription. Duet Display is available from the App Store. [Direct Link]

[doublepost=1522523595][/doublepost]I have written the Duet support team and this is the reply I received this morning (Mar 31):

We're testing a new version of Mac app internally, and it should be available in a few days unless further issues arise. This version has a better compatibility with High Sierra 10.13.4. I hope you can bear with us a little longer.

If it’s a deal breaker for you, you can request a refund through the App Store by following these steps:

So... according to this email, there will be a fix shortly. Let's hope.

how did you revert to 10.13.3?

The system will take a local snapshot before you update. If you boot into recovery you can revert to this snapshot.

Remember to copy any new data you have since the update to an external location BEFORE you do this as the entire system gets rolled back including your data.
 
I use a Wacom intuos for a mouse, so Duet hasn't really worked reliably for me since the beginning. It looks great, but the while the desktop expands on to the iPad, changing the size and shape of the cursors area, the cursor itself hits a wall and won't travel on to the Duets desktop. Any amount of rejiggering settings only fouls the cursor completely off both displays.

Apple really needs to build the option to use an iOS device as an external display right into Mac OS as an Air Display option, extendable or mirrored, and whether over USB or not, & do it right. And buy these guys and have them work on it, if Apple has any scruples.

it is impossible to boot into recovery on my MBP 2012 - I tried it a couple of time and it seeks internet connections and nothing happens.
 
My rumor: Apple will add its own implementation on AirPlay3 which will work only on the latest Mac, iPad and iPhone. They don't need others offering the same solution for previous models.
 
I’ve been saying this for a year now and it still holds true: if you rely on your Mac for work, you can no longer trust Apple.

I have lost all faith in Apple’s ability to release software updates that do not break critical functions. There has not been a single major dot release in the last two years that has not broken something critical to my workflow. Not a single one.

After High Sierra is stable, I will not update my Macs for nearly a year until the next OS has stabilized. It never used to be this way with Apple, but unfortunately, this is what they’ve become.

Never been this way? Dude, it's been this way since Jaguar. Even back then on the Apple boards people were warned not to update until the mid iteration of the os. x.5 or x.6. And to leave those after it alone as Apple would invariably break stuff to get in the hooks for the next buggy OS until x.5 or x.6 where it would be stable. I don't know, maybe it was just a pro apps thing because new versions always broke something either in Logic or FCP.

Apple ALWAYS counts on the early adopters to do the real en masse beta testing.

I'm still sitting here on Sierra with a spotlight that will never work again probably.

To be fair, Duet Display is essentially a hack. It isn’t as if Apple intended the iPad to be used as an extended display for a Mac. If they did, they’d have built it in themselves.

Still, they’re happy to take 30% of each Duet Display copy sold.
[doublepost=1522586069][/doublepost]As soon as I installed Duet Display on my Mac, I lost the option to Airplay content to my Apple TV. Apparently, that’s a known issue for years and it would require Apple to address it. Duet Support stated that would not happen.
So I deleted their app.

Although I do like its functionality.

Is it really a bug or did Apple intentionally change things that happened to break compatibility? Might not be a bug, and just the outcome of system changes to macOS

i was thinking the same thing. is it not actually a 'bug' but that the apps need an update to work with the new version and it hasn't been finished by the developers
 
Perhaps it’s time for Duet to update their App info on the App Store to say that it’s broken in 10.13.4..as of now they’re still selling it to unsuspecting users.

They can't do that because new App Store requirements only allow developers to change developer notes when submitting an updated application. :)
 
My big disappointment is that the Duet team did not sent email to registered customers of the product alerting us not to update to what appeared as a minor bug fix release. Surely they must have know there was a problem weeks in advance? I always wait a long time before taking major and dot releases, but I do keep up with patches that might include security fixes. It kind of feel like banging into one of Apple's glass walls -- never saw it coming
 
Hmmm....I use one every day for work (network engineer) and I would not have it any other way.

My only real complaint is when I have to use my USB to serial adapter to console into piece of equipment on site. USB-C to USB-A dongle, Keyspan USB-A to serial dongle, null modem cable to device or serial to ethernet to device. It is quite the frankestein setup in those cases....but it works every time.

Dump the daisy-chain of port death. I've been using USBA-Cisco Console cables for some time now, and I just ordered some USBC-Cisco console cables from the same vendor. I'm sure that you've found that it's important to use a good conversion chipset (I find FTDI-based devices to be the most stable, watch for grey market / counterfeit chips).

Hey, at least the new gear is switching to Bluetooth....
 
Yes it did. People have ALWAYS said this.

I remember Snow Leopard wiping out people’s entire home folders. And 10.2.8 killing Ethernet. Etc.

Yup, was going to post the same thing. Apple software has been buggy for awhile now. Long before HS. There has always been posts about not trusting Apple for "real work", losing faith in Apple, and the list goes on and on. Quickly how folks forget or who are "new" to Apple.
 
I'm wondering if your frustration is with multiple bad instances, or just with the Duet issue. I would say that if having additional screen space is a "critical function" that you shouldn't be using Duet and should purchase an additional display.

While I have a second display at home, shipping a monitor would be somewhat inconvenient; so I also use Duet when traveling. It is really nice to have a second display simply by attaching my iPad Pro to my Mac. For example, on a recent rip I used Duet to display a reference document while I edited two others on my Mac. Yes, I could have transferred the document to the iPad and scroll thorough it natively but then I could not cut and paste easily between the two devices. Universal Clipboard isn't a good replacement for native cut and paste.

I've used Duet since its initial release and recommended it to many others; I hope the developers come up with a permanent fix.

Considering they would have had access to the Dev BETA, this is something they should have sent notice for.

Next questions after why they didn't alert us, is can they resolve it, and if not, who do we go to for a refund?

Update: Users of other desktop extension apps like Air Display and iDisplay are also reporting incompatibility with macOS 10.13.4. DisplayLink-enabled USB graphics devices are also reportedly affected. There's some speculation that Apple's added eGPU support in 10.13.4 is the underlying cause of the issues. We'll keep readers updated if we hear more.

That is why Apple pre-releases their next software up date and next major OS version via the Developer Beta Program and the Public Beta Program. Failures like this can be completely avoided if the software developer reads the notes that Apple issues as well as test their software before Apple releases it. Developers that do not perform thorough compatibility and performance testing are the ones to blame, not Apple. Its Apple's job to keep pushing their OS forward, which by definition requires change.
 
From their Twitter page (link), it looks like the Duet team has known about the issue for quite some time now. I really wish they had notified users before we all upgraded.
