I'm experiencing a new crazy issue.  I have about 9 MAC computers on a network with mostly Windows PCs.  I have a windows 2012R2 DC, with AD, DNS, DHCP, etc...
If the Macs use a static IP, everything works fine, the hostname stays what is configured by the user.

As soon as I change the manual IP to DHCP on the MAC, after a reboot, the hostname of the PC randomly changes to a windows PC name.
It's completly random, as different MACs use different windows PC names.   Where do I even begin to troubleshoot this issue.

I am running different versions of the mac, on most of the macs, i'm running Mojave.  A few are running Catalina.

Budget: $200 or less

There will be about 20-30 wireless devices using the router habitually.  I also work from home some days.  I currently have an Apple Airport, but was looking to replace it after the 5 years I've had it.  Apple doesn't make them anymore (I heard that somewhere) so was curious what others recommend nowadays.  I've used Netgear, DLink and Linksys in the past.  I'm down for whatever really.  I'll probably be purchasing it on Amazon unless Newegg or something else has a better price that you know of?

Thank you so much.

MAC OSX and Exchange connectivity problems.
I have a few OSX clients, newest version having mail connectivity issues.  I host my own exchange 2016 server, and none of my windows users are having this issue.
I have mac is hard wired and the other is using wifi, and both are having issues sending or receiving emails.  Looks like the mac mail client has issues connecting.
I can ping my exchange server just fine from the work station and since my PCs are not having this issue, it leads me to believe it's something with the OS client?
The Exchange server and the macs are on the same network.

When trying to send an email, it just sits  in the outbox until it goes out by itself later.
Or there's an error message stating to select a server.
It's random throughout the day.

If anyone has experienced this before and knows what is causing the issue, I would be so appreciative to figure this out.

Hello,

I have an issue with disappearing shortcuts of shared folders between two mac machines. Here is the case in details:

On MAC1 there are 10 folders on the desktop that are shared on the network. They are accessible and visible on MAC2.

When I created shortcuts on the desktop of MAC2, they work fine until MAC1 is rebooted. Then a warning message appears and shortly after that the shortcuts are gone.

Is there a way to resolve this issue?

MAC1 is running macOS Yosemite 10.10.5

MAC2 is running macOS Mojave version 10.14.3

Thank you

Hi

We are a school and we started buying iPads for the staff. I have created a school iCloud account.  

Please let me know if there will be a way of adding new iPad to the school cloud account and once the iPad is given to staff they must be able to install apps by their own.

But when they leave the organisation , they should return the iPad , but able to carry the paid apps and install on their iPads they wish.

Please let me know a best way of setting up this.

Any help will be great and thanks in advance.
Thanks

Have a customer who has been running a Mac - connected to wifi on a Mikrotik RB951 router/access point. Has worked well for a long time. The Mac is around 10 years old.
When trying to connect to his wlan recently he couldn't see the wlan. The Mac detected, however, a couple of near-by networks.

I did some checking and found that I could  see the network and log on from my windows PC and from my Samsung phone without any problems. Customer could also see the network and log on from his iPhone. Tried to define a new network on the Mac by entering the ssid and the password, but got message "Network not found".

Tried to turn off the WPA2 encryption and run witout any encryption, and then he could connect without any problem.

This problem seems to have shown up after upgrading to Router OS 6.43.8.
Downgrading to previous version (6.42.6), but it didn't change anything.

Had a very similar problem with another customer also with a Mikrotik hap ac lite. After upgrading to Router OS 6.43.8, apple devices got connection problems. Replaced it wirh a Ubiquiti unifi ap, and the apple devices started to connect properly again.

Any ideas why Apple produkts seems to have these wifi connection issues?

P.S.  Have also posted this quesiton in the Mikrotik forum.

I have had a few people tell me that when trying to visit a site using safari on their iPhones, they get an error that says:

Safari cannot open the page because the server cannot be found.

I asked other people to test on their iPhones and they said it works fine. After asking Google about this it seems that the answer is always something to do with the phone itself. But, it is not realistic to ask everyone with an iPhone to check this setting, and check that setting in order to try use the website.

Does anyone have any suggestions regarding this?

What's the best way to update Mac mini "Core 2 Duo" 2.4 (Mid-2010) from 10.6.8 to either El Capitan or Sierra or at least something newer than 10.6.8. We do not mind doing fresh install. We have other El Capitan Mac which we could use to create an installation image. Can we just install El Capitan and will it automatically activate and not ask for licence serial number? Will drivers still be available?

How can certain usernames be hidden from the Mac OS X logon screen window when the login window is displayed as a list of users?

We want to keep the list of users view (and not switch to the "Name and password" option and want to simply be able to hide certain usernames from appearing in this list.

How can this be done?

This needs to be done within a macOS High Sierra version 10.13.4 OS.
