Which phone number is shared by Apple Pay in a dual SIM iPhone?

When adding a card to Apple Pay, it says that your phone number may be shared with the bank who emitted your card. But in the case of a dual SIM phone which number is shared? If you have a personal phone number and another one, can you choose which one will be shared with the bank?
Have anyone a personal experience with a dual SIM phone and Apple Pay?

Why doesn’t Apple market more aggressively to the business market?

Apple focuses primarily on education, consumer and professional media production markets, but generally ignores the more profitable business sector. Nevertheless, the stunning success they’ve achieved in their core markets is truly mind blowing. Apple’s ecosystem is exactly what every business has been begging for and what every tech company dreams of delivering. None of them nail down the seamless communications, the low total cost of ownership, the data security, the low learning curve and the productivity as exquisitely as Apple does.

Yet the vast majority of the businesses are unaware of these advantages and Apple does little to change it. Apple, for instance, failed to position FaceTime as a business video conferencing platform, allowing Zoom Communications, a startup, to become the standard for video conferencing. In sharp contrast, Apple’s iPod and iTunes consumer products managed to dominate online music and even rescue the music industry from near collapse, despite competing against freely downloadable music.

With its recent introduction of the M1 chip, the business market is Apple’s to lose. The incredible performance, energy efficiency and low cost makes this chip a no brainer for business computing and servers. I can’t see a compelling reason why it would not want to aggressively expand into Intel’s territory. Considering the flattening of its main product line over the years, the business market might provide Apple another avenue for continued growth. So why isn’t Apple more aggressively marketing to the business market?

encryption – Apple Platform Security and NAND flash storage

I’m busy reading the Apple Platform Security document and I have a few questions regarding it.

The passcode is entangled with the device’s UID, so brute-force attempts must be performed on the device under attack.

Questions: Does this mean that if the device is physically damaged, the microchips cannot be taken out and brute forced on another device (PCB/FPGA)? If yes, what in the hardware prevents this? If no, what level of damage would render the NAND flash storage useless and the data unreadable?

Would repeatedly hitting (7-13 times) the back of the iPhone with a 6 pound hammer render sufficient physical damage to prevent information recovery?

The iteration count is calibrated so that one attempt takes approximately 80 milliseconds. This means it would take more than five and one-half years to try all combinations of a six-character alphanumeric passcode with lowercase letters and numbers.

Questions: Would an attacker ever be able to actually perform this password guess over the 5 1/2 years’ or would the maximum 10 attempts kick in and actually prevent this?

If the maximum attempts would prevent this, is this protection built into the hardware (Security Enclave)?

How many years would it take an attacker to brute force all combinations of a seven, eight, nine and ten-character alphanumeric passcode with lowercase letters and numbers?

Does the 2020 Apple M1 MacBook Pro support 2x daisy chained Thunderbolt Displays?

The Apple Silicon based 2020 Apple M1 MacBook Pro supports Thunderbolt version 3 and I’m wondering if anyone has tried connection one to an Apple Thunderbolt Display?

Of course you’d need to use one of Apple’s Thunderbolt 3 to Thunderbolt 2 converters.

I also understand that this version is limited to supporting only a single 4K or 6K display, but since the original Apple Thunderbolt Display is only 2K, could I daisy chain 2x such displays? If you’ve tried it out please share your experience.

audio – Controlling a Sony Bravia TV and sound bar with an Apple TV

hopefully, this is the right forum, for this question because I have no idea who else to ask.

I want my apple TV to control my TV and soundbar. This includes sleep/wake functionality as well as volume and mute.

My soundbar can be connected by an optical cable or HDMI. As I understand it, optical cables are incapable of passing signals (on/off/volume), and only pass data. based on what I have observed this appears to be true. If I plug in the HDMI cable from HDMI2 on the TV to the HDMI3 port on the soundbar(Only port on the rear of the unit), it will turn on and off with the TV remote or the Apple TV remote and volume and mute controls work. The only issue is, when I turn on the Apple TV, it signals the TV and soudbar to wake and sends a signal for the TV to switch to HDMI1 (The HDMI port that the Apple TV is plugged into). The problem is that either the TV or the Apple TV is sending a signal to the soundbar, setting it to HDMI1.

If I unplug the HDMI cable between the TV and the soundbar, just using the optical cable, and set up custom IR controls for the soundbar in the Apple TV remotes menu, I am able to adjust sound and mute, but there is no other connectivity. The good part is that the input does not change, but the bad part is that the Apple TV isn’t able to turn on/off the soundbar.

This has to be a common configuration. Has anyone else worked around this?

macos – Does trustd leak information about users’ software usage to Apple and/or third parties?

The best technical write up I have seen of what in hindsight looks like a rookie mistake by Apple (I’m not saying it was a rookie mistake, just all signs I’ve seen point to inadequate engineering and poor technical choices).

The failed or congested OCSP service did cause a very widespread denial of service outage on macOS client computers November 12, 2020 for more than 90 minutes.

A crucial difference between OCSP and notarization is that the latter is only checked on first launch of the app. The notarization status is cached permanently and has no expiration, unlike OCSP. Thus, notarization only affects your ability to install new apps, it doesn’t affect your ability to launch already installed apps.

How to disable DoH and DoT network-wide for Apple iOS and macOS

I am running an the Open Source OpenWrt router firmware and wish to disable DoH and DoT for the whole network. In my network lots of latest iOS and macOS devices.

To disable DoH for Firefox is used this guide Canary domain – use-application-dns.net. I search for a similar solution for Apple based devices.

Operating systems Apple

Apple’s iOS 14 and macOS 11 will support both DNS over HTTPS and DNS
over TLS (DoT) when they are released in the fall of 2020.
