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

Hi! Before iOS 13.0, the only way how to connect to BT classic device was External Accessory framework and the device had to be MFi licensed. Now that I can use Core Bluetooth to connect to BT classic device (custom manufactured device that should support GATT over BR/EDR), does manufacturer of the device still need to join the MFi Program?

After updating to macOS Big Sur ver 11.0.1, Mac Book Pro MacBook Pro (Retina, 13', 2014) doesn´t recognize anymore two additional displays connected through i-Tec USB 3.0 Docking Station. Reinstalling driver Display-Link and i-Tec Driver hasn´t solved the problem.

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?

Whelp, I learned a lovely lesson about Lacie today. Their customer driver extensions on MacOS are ultimately as bad as I figured they would be and it seems to have bitten them in the ***. It seems their current drivers aren't compatible with M1 Mac minis (and I haven't seen a single post/article mentioning this). I was planning on migrating my Plex server from an i3 Mac mini to an M1 based device, but now I have to reshuffle my setup with another one of my computers due to lack of driver compatibility (and no advertised lack of support). I'm seriously considering getting rid of my Lacie 6Big at this point and swapping it out for an OWC thunderbolt 3 rack supported DAC. -\_-. I'm hoping other people just read this because honestly, I have nothing but nasty remarks towards Lacie in this regarding considering their #1 use for their RAIDs involves the people who will be buying M1 Macs. Does anyone have a workaround for this?

The iMac runs perfectly when no external monitor is plugged, but as soon as the monitor is connected it crushes within an hour. Did anyone found any solution to this problem? It happened both with Catalina and after updating to BigSur Thank you in advance to anyone responding.

We're trying to start ATS in Mac, however, we get the following error message: ATS has detected a problem with your installation. Please reinstall ATS After this, the application terminates. We also have tried to use another user and to install this application into another Mac, but still have same problem. Currently we're using Catalina 10.15.7 and only have Lighning Box connected.

I’m trying to read the battery level of a connected Apple Watch on an iPhone app. The built-in iOS Batteries widget shows the current Apple Watch battery level, so I know the data is being sent from Apple Watch to iPhone frequently, however I could not find a public API to read the level in my iOS app. My best solution so far was to build an Apple Watch app that periodically sends the battery level of the Apple Watch to the iPhone using WatchConnectivity. Then, I found this app. It can show the battery level of my paired Apple Watch without ever installing an app on the Apple Watch. To try to accomplish this same thing, I have tried a few different approaches. First, I tried Core Bluetooth, but after a lot of exploring, troubleshooting, and asking at a Core Bluetooth lab, I’ve ruled that out since Apple Watch does not expose its battery information that way. I experimented with the External Accessory framework, but that doesn’t seem like the right approach either, since it's for MFi accessories and I couldn't find a way to get Apple Watch info with it. How is it possible to read the Apple Watch battery level in an iPhone app without sending it from a companion Apple Watch app? Or is the app I linked to probably using private APIs?

I have an iphone 12 pro. Since update 14.4, Bluetooth has been disconnecting randomly from my Airpods. Then when I updated to 14.6, it started happening more frequently. I thought it was my Airpods, so I bought a pair of brand new pair of Beats Pro Wireless (true wireless). It's still happening and still the most irritating thing about my apple products right now. Halp.

(Before I begin, it might explain quite a bit if I note that the only reason I had not yet posted this question here is that I was not aware I could do so. Otherwise, I would have, years ago.) Some important acknowledgments: iPhone (iOS) currently supports Bluetooth Keyboards. In fact, it is being actively developed on at this very moment. I know this because I have been documenting (via blind test) Bluetooth Keyboard shortcut alterations in Safari between iOS 15 dev betas. When iPad OS was split, so too were both the user-facing and dev-facing official documentation of the operating system’s native support (shortcuts, really,) from Apple. When this happened, the docs all but stopped acknowledging iPhone’s continued support because the goto iPad doc - “Learn iPad keyboard shortcuts” - does not have an iPhone equivalent. Pretty much all the iPhone User Guide has to offer is a howto on pairing. This split - combined with the explicit product introduction of a magic keyboard dedicated to iPad - has resulted in (as far as I can tell, as a non-developer) an overwhelming state of confusion regarding the whole idea of using a Bluetooth Keyboard with iPhone. I have spent the past few years talking to developers who somehow did not know their iPhone apps had working Bluetooth Keyboard shortcuts. I have made it a habit to just write the shortcuts tables myself by way of blind testing off the handy iPad guide which appears when ⌘ is held (not on iPhone!) There really are those of us who regularly use Bluetooth Keyboards with our iPhones. Most I have met do so for what I would definitively classify as Accessibility concerns. (My personal use is not quite definitively so.) My question, really is: Where can I find complete documentation of both keyboard shortcuts support in native apps/the OS and UIKeyCommand’s uniquely-iPhone considerations? (Please assume I have seen any related docs on developer.apple.com and support.apple.com.) I’d like to leave it there at the risk of being uselessly verbose. Thank you for your time. I look forward to hearing back.

Same issue submitted since first Beta version 12. Have Apple bluetooth and USB keyboards. Tab will not tab from cell to cell or section to section in Excel desktop, or any online form. Space bar does not scroll pages. Rather, it opens program window to full screen zoom. Menu bar Bluetooth recognizes keyboard. Pref file can never find it. Monterey is useless without properly functioning keyboard. Tried resetting actions. No luck. Help appreciated.

Hi, I want to know if there is a roadmap for implementing RFCOMM support in iOS. We have a SOAP/Rest platform (wse.app) which makes it possible to do SOAP calls between Android and Raspberry Pi over Bluetooth/RFCOMM. When will Apple implement support for RFCOMM so I can use my iPhone and do the same ?

I have an iPhone 12 and I paired it with a bluetooth device in my house. So when I try using my iPhone on the house, I have to click that I am not driving to open my phone. How do I change the settings to stop this? I tried the Bluetooth volume leveling setting but that has no effect. Evidently, only volume is affected and the phone does not use it for anything else. Otherwise, I have to disable the entire function.

Bluetooth Connection Issue: In iOS 14.7.1 and above (iOS 15.0 beta), observe a sudden drop in the connection between the App and the external BLE device during the firmware upgrade process via Over the Air (file size 500 KB, file type ".bin"). The same App is working fine with iOS 14.6 and earlier versions of iOS. It observes that MTU size is also different in iOS 14.4 and iOS 14.7. When disconnection happened CoreBluetooth -> centralManager: didDisconnectPeripheral delegate method called. The total time required to update BLE firmware is 2 minutes, but approx after a 1-minute or 30 seconds connection is dropping between the App and the BLE device. Do I miss anything that causing a sudden drop of BLE connection, specifically in iOS version 14.7 and above?

We are using a vendor-provided SDK to access their hardware through EA framework and intermittently the EA framework streams stop working (in particular, the input stream reports 0 for hasAvailableBytes). In some cases, this situation persists until we detach the device and reattach (this is via a lightning connector). After installing the IAPD debug profile and retrieving logs, we notice a few interesting log entries from the syslog we retrieve off the tablet. I am trying to understand and make sense of this and determine how this can be fixed.
