INCOMPATIBLE DISK error message upon launching Big Sur APFS vs MacOS Extended issue in Big Sur?
Running on: iMac 27" 5k late 2015 - 64gb ram and a 16tb Pegasus Promise2 R4 raid5 via Thunderbolt. After trying Big Sur - found issues with Luminar Photo app, decided to return to Catalina on the iMac. Reformatted my internal drive and reinstalled Catalina 15.5 and reformatted the raid. But I keep getting the following message upon restarting: "Incompatible Disk. This disk uses features that are not supported on this version of MacOS" and my Pegasus2 R4 portion no longer appears on the desktop or in Disk Utility... Looked into this and discovered that it may be an issue of Mac OS Extended vs APFS The iMac was formatted to APFS prior to installing OS11 so I reformatted to APFS when returning to Catalina. The issues persisted so I re-reformatted from a bootable USB - this time to Mac OS Extended (journaled) and the issues seems to be resolved. The iMac runs slower on MacOS Ext, but it is running and the Raid is recognised... I'd love to go back to APFS but am afraid it will "break" things. Any thought on this would be welcome. Thanks Nick

Why doesn’t my Magic Keyboard Tab through Playgrounds Code Completion choices
I am following Jonathan Penn’s demo at WWDC2019 where he tabs through code completion choices with the external iPad keyboard. The difference is that this does not work with the Magic Keyboard on my 2020 iPad Pro 11” - the Tab key has no effect whatsoever on the Playground page whilst I am coding. I have to tap on the code completion to choose it. I can’t see any setting that I need to make but cant believe this is what it supposed to happen.

Warning on sticker pack submission - ITMS-90863
I am able to upload a sticker pack but with the following warning: ITMS-90863: Apple silicon Macs support issue - The app has LSApplicationLaunchProhibited set to true. This is not supported on Mac. I understand this limits the ability of the sticker pack to be used on a new silicon Mac. Is there a way to change this flag so that this generic sticker pack will work on a Mac?

2020 Macbook Pro will not recognize any HDMI connection running Mac OS Big Sur
Prior to downloading and installing Mac OS Big Sur, I was able to connect my 2020 Macbook pro to any HDMI monitor/tv. Specifically I would mostly use a Dell se2717 monitor. It would connect within a few seconds and there was never any issues. Once downloaded and installed Big Sur to my computer it no longer recognized any HDMI monitor/tv. I have tried different adapters to connect the HDMI cable to my USB-C ports; different USB-C ports with all the adapters; and tried every trouble shoot I could find from Apple, Dell, and various websites. Is there anything I can do to fix this issue?

iPAD Pro External Camera
Hi, I was trying to configure people with the iPAD as a primary system. They got the apple keyboard, mouse, and an external monitor 36in. However the external camera via USB or bluetooth cannot be used for FaceTime, Webex, Zoom, Teams, etc. It always default to Apple camera. Is there a way to get an external camera and apps to recognize as the primary camera on an iPAD. Thanks

Using Wallet.app to open doors with NFC reader
G'day. At my office the doors are locked with an NFC reader. We carry around a little NFC tag on our key chains which will read out a number and this then will open the door if the number matches a number in the database. I am tired of carrying around the tag, people keep loosing it, forgetting it and it would be nice to open the door using a Phone - which we tend to always have on us. So I used a credit card which is NFC enabled to readout the NFC information, added this number to the database and can now open doors using my credit card. This is pretty cool. If I forget my keys (most likely they will be on the desk but silly me left the desk without them), I may have my wallet with me. Then I tried Wallet.app on my iPhone and select the same credit card. However the door doesn't open. When looking in the door software I noticed that the tags will always transmit the same number. So does my credit card. However Wallet.app will read out 4 readings (or maybe just one very long one) and they are always different. So I can not make them match with the door database. Any ideas how to make this work? Can I give somehow wallet.app an NFC number which I can then add to my door database? Or how come the credit card and the very same one in wallet.app don't match? Thanks for your help! Would be neat if I could make this work out. This will make a lot of people happy at my office! Cheers!

Core Ml Model, labels probabilities returning nan
Hi, I have a core ml model that when I try to print the: modelPrediction?.labelProbability which is of type String:Double and contains all the features with their corresponding probabilities, the value of type double comes with nan rest = nan right = nan up = nan Sometimes restarting makes it work again. Sometimes it can take a lot of restarts to start working again. Even when deleting the app and installing again the same thing happens. Also tried changing the deployment version but didn't seem to fix it. Any help is appreciated.

How to monitor Neural Engine usage on M1 macs?
I'm now running Tensorflow models on my Macbook Air 2020 M1, but I can't find a way to monitor the Neural Engine 16 cores usage to fine tune my ML tasks. The Activity Monitor only reports CPU% and GPU% and I can't find any APIs available on Mach include files in the MacOSX 11.1 sdk or documentation available so I can slap something together from scratch in C. Could anyone point me in some direction as to get a hold of the API for Neural Engine usage. Any indicator I could grab would be a start. It looks like this has been omitted from all sdk documentation and general userland, I've only found a ledger_tag_neural_footprint attribute, which looks memory related, and that's it.

Identifying Unknown Third Party Spyware App
Unfortunately I have found myself in a very messy and painful situation, I’ve been dealing with for the last 4-5 months (at least). That situation being my ex girlfriend installed a Third-Party Spyware application on my iPhone 12 Pro and or iCloud account. This has had almost uncomprehending negative effects on every corner and facet of my life, including my my relationship with my daughter, my family, my friends, my ability to successfully conduct and manage my business, my finances, etc. I’ve spent 1000’s of hours studying how, why, and what she has done to gain access to basically to most my entire adult life and all the data that I’ve accumulated during it (dating back to 2010), and lost days of sleep from the anxiety it’s brought on (my photos and data have been used “anonymously” and maliciously, via harassment, stalking, anonymous slanderous character ************* campaigns on many occasions). If there’s anyone out there that could possibly help me identify how and what this woman is and has done to lite ablaze this seemingly never ending inferno in my life, I would GREATLY appreciate it. Thanks in advance and God Bless! Roger Beaman 817-966-0819

EtreCheck (from Etresoft, Inc)
Hello I've noticed that this product, heavily promoted on the ASC forums for many years, is no longer available from the Apple App Store. Can anyone tell me the reason why the product is no longer supported? Friends have asked me if it is 'safe' to use. Is it? Note to moderator: If I'm asking in the wrong places, please redirect my question. Thank you.

TotalSpace3, Apple please wake-up!
Apple Please! Since your last OS update the most useful software on Mac: TotalSpace3 stopped working. TotalSpace brings the ability to navigate in the spaces through a grid of multiple 2D spaces (like it was 10+ years ago on Mac). Since TotalSpace is not working anymore (and exists and work on Linux) it became less interesting using a Mac... I can't believe that no one at Apple is using TotalSpace ?! It's just impossible to work on a Mac without it !? Navigating with the native Apple horizontal space means that we have to click (and wait 5 seconds) to navigate between space 01 to space 10... Are you serious at Apple ?! only my Grand'ma navigate into spaces with the Apple native interface... With TotalSpace, we can (could) swipe with 4-fingers on the trackpad and change of spaces in two dimensions (01 > 10 in half of a second). IT'S VITAL for people who are intensively using their mac. Ex: [01][02][03] [04][05][06] [07][08][09] You're digging your grave! Developers: who were all (the good ones) using TotalSpace will move to Linux without it, as it became impossible to use a Mac without it...
