To add to @nohillside answer you can share a FAT32 formatted drive but not set permissions as the filesystem doesn't support it. If you want to control access to files on the USB by permissions then format it using a filesystem that supports it (such as HFS) and changes will be avaliable in File Sharing.

ExFAT/FAT32 don't support file/folder ownership, so you can't assign access rights or users to them (neither for local use nor for sharing).

Apple's application firewall is designed to have many exceptions to work with its services so the system prefs will take a lot of clicks. I will suggest a more command-line way to accomplish this large change in port access for the built-in pf firewall (no need for extra software). Here is a simple rule set that will block all traffic except for ports 80 ...

Regardless of how you connect to your iPhone acting a a personal hotspot, whether it be via WiFi or tethered via cable, you are sharing the cellular data connection. So, using your example, where your iPhone is initially connected to the corporate WiFi and then you enable the Personal Hotspot feature, you will disconnect from the corporate WiFi and a ...

Network Utility is using ICMP rather than the default UDP protocol used by traceroute. You can use the -I flag to get the same behaviour on the command line: traceroute -I 173.194.33.116 I don't know of any way to force Network Utility to use UDP. One explanation for this could be that your firewall/router is configured to block ICMP packets.

Buy the dongles. I worry your company is able to secure these if it isn’t budgeting for training and support let alone very inexpensive adapters. There’s being frugal and then there’s “we’re not even thinking about selling one Mac” to fund to what needed to run the rest of the fleet. If your labor is cheap, make cakes and cookies and sell them to fund ...

MacOS can have multiple network connections, via WiFi, Ethernet, Thunderbolt and indeed USB. Normally, one network takes preference over another: if the protocol can't be established on one network, it will look at another. In this way, it's possible to have Internet, file sharing, and other network devices like printers all on separate connections and ...

Here's a one liner and the thread where I learned this a while back: sudo networksetup -setdnsservers Wi-Fi "Empty" After using `networksetup -setdnsservers Wi-Fi "8.8.8.8" "8.8.4.4"` how do I clear them?

This is intended behavior. Content Delivery Networks such as Akamai work by getting the data closer to the user so that downloads and other interactions perform better. The way this is done is to have multiple servers located all over the globe. You will in general then be using a server that is near you - i.e. if you're in France, you could be using a ...

I found the solution to my issue. I was attempting to connect with the wrong hostname. Bottom line: Double, no, triple check the hostname you're connecting to. A lot of these types of issues is caused by innocent, simple mistakes such as this.

There should be a "Parental control" option in your router, from where you can set up rules for access. You don't mention any specific router brand, so I can't give you a specific how-to.

networksetup -listallnetworkservices is the macOS command that I believe you are looking for. Quoting from man networksetup: -listallnetworkservices Displays a list of all the network services on the server's hardware ports. An asterisk (*) denotes that a network service is disabled. On my MacBook Air: An asterisk (*) denotes that a network ...

Names aren’t associated to adapters, it’s the hostname of the computer. Why it’s the WiFi and not the LAN is basically which one got assigned first. You only have one entry because, well, you can only have one. Many routers have a mDNS service (usually attached to DHCP) that manages the resolution of host names to IP addresses. This is a 1-to-1 ...

The Service Order doesn't work. If you test it, you will find that Mac OS prioritizes Wifi over Ethernet, even if Ethernet is set higher in the Service Order. One way to test it is to measure your bandwidth (e.g., https://www.fast.com) in the following scenarios: Connected to Wifi, with Ethernet unplugged Connected to Ethernet, with Wifi turned off ...

A macOS server system provides two and half firewalls: Application Firewall (with a GUI > System Preferences > Security & Privacy) pf (only 3rd-party GUIs) Adaptive Firewall which is (or at least was) based on ipfw and pf (and thus in parts flawed because Apple botched it by removing ipfw). Partly fixed here: How to setup the adaptive firewall. Only ...

Other than Ngrok, ssh.localhost.run is excellent for that purpose. You need to have the Openssh Client. Use :- ssh -R 80:localhost:port ssh.localhost.run Replace "port" with the port your server is running on. You will receive a link, just like Ngrok, you can use that link. Other than localhost.run there is also serveo.net, use it the same way as ...

Originally, in Mac OS X 10.2 in 2002, the central purpose of mDNSResponder was to respond to Multicast DNS requests. Nowadays mDNSResponder is responsible for Unicast DNS as well as Multicast DNS, for both hostname lookups and service discovery. It also manages other networking functions, like “Wake for network access”. Disabling mDNSResponder would break a ...

SMB is not disabled, but netbios name resolution is. See this answer to test if you just need to set up DNS or reactivate netbios. What causes some Network Drives using SMB no longer connect to macOS Catalina? You can always connect by IP address to test if it’s name resolution before changing your preference files or altering the system configuration.

There’s definitely a bug somewhere. I’ve deleted the Time Warner profile, reset my iPhone X running iOS 13.3 network settings, and rebooted it several times. When I click the info button for the secure TWC passpoint network, it does not show the usual auto-join, auto-login, or “Forget this Network” buttons. My phone is still trying to connect everything ...

In my case the high pings were caused by the Deepl application. Hope this helps somebody.
