When I insert my Transcend 64GB thumb drive & Western Dig 4TB USB HDD to my teen kid's
Macbook Pro running OSX 10.11.6, both devices are auto-mounted as I can see from  Unix
command "df "

However, I can't copy files into the Western Digital USB HDD (it's partitioned into 2x 2TB)
though I could copy files into the thumb drive.  Both USB devices are formatted as NTFS.
Can't recall the error message that I got but I can test it out again in 3 hrs time.

What's the reason & how can I fix it such that I could copy to the WD HDD?

Basically I just issue the Unix "cp " or "mv " to copy files from the MAC to the /mount
names of the USB devices.
One of our users has a personal Macintosh computer that can't access any regular external Web sites when on our corporate network.

In Safari, she gets the message:

Access Denied.
Access control configuration prevents your request from being allowed at this time. Please contact your service provider if you feel this is incorrect.

Other browsers produce a similar result.
Ping and DNS resolution work when the computer is connected to the corporate network.

The computer works can access Web sites normally when on a non-corporate network.

All other Macs on the network function corectly. We don't use a proxy server.

Any thoughts?

As a recently new macOS user, just started using the Calendar built into macOS Mojave (10.14.4) I am a bit annoyed by the rather small size of event windows.
I'd thus be happy for a way to increase the size thereof.
Unfortunately neither the built-in nor the online "Calendar User Guide" provides a solution, nor could I find one searching the Internet.
Changing screen resolution, switching to another Calendar application are not feasible options to me.

On a mac, I have a program that can send an email of some date. We are trying to use Thunderbird instead of macMail. I have the default email client set in Mail's preferences as Thunderbird but the program keeps grabbing the macMail client for sending this information. This is happening on all workstations (this is a dental practice management piece of software.) I checked with the software company and there are not settings within the program that control what program is used for email and is selected through the defaults. I have not been able to find anything on this via Google. Any help with this would be appreciated.

BTW: The OS is Sierra,10.12.6


Hi Experts;
I have a complex .xlsb file with many macros, pivot tables, VBA function, external sql connections, controls.
My managers would like this file to be runnable on a Mac.
I've searched EE and i-net. The conventional wisdom appears to be that Excel and macros can run on a Mac.
I had a friend test the file and invoke some of the macros on his Mac - he was able to open the file in Read Only, but invoking the macros gave him 'Security Warning - External Data Connections have been disabled'.

He does not have 'Developer' enabled on his Excel version, so that may account for some of the issues.

What I have been asked to do is find out what is needed to run this file on a Mac,
I have not been able to find definitive answers for:
1. What version/OS on the Mac is required. Is there a minimum version of Mac Excel version?
2. Would enabling Developer allow for the external data connections?
3. Would enabling Developer allow for the VBA macros?
4. Maybe there is an emulator I can try?
5. Running Windows in a VM or bootstrap partition is not an option for our customers.

I suspect we will need trial-and-error to ensure all pieces of this file run, but I am a tad handicapped as I don't have a Mac, and outside of begging my family and friends to compromise security on their apple devices (not going to do that), I don't have access to a Mac.

If helpful, an abbreviated version of the Excel file is attached. It has all the bells and whistles but the data is less…
I have 2 Macs/Mojave and one account. I updated App ID password on Mac #1 (Why? because previous password no longer worked - Why ???)

Now the fun begins [read torture]...

1. Change password on Mac mini/Mojave #1...
2. Spend time entering 2-factor ID 6-digit code (Wait! - do I have iPhone at hand? - yes, whew!)
3. Ok, now able to open account with new password

4. Go to Mac mini/Mojave #2...
5. Login to is NoGo using password as updated (changed) in 1-3. above

This is the second time I have been down this road. I don’t know why new password (#1) was required, and worse working iCloud password on Mojave #1 again does not work on Mojave #2.

It gets worse…

Any ideas why this password is not valid on second Mac?

[Next Day] - Any ideas why Password (see 3, above) is ‘invalid’ next day on Mac#1?

That is, I cannot login to from Mojave #1 or Mojave #2

Of course, I can (I assume) create a new Apple ID / Password - is this good idea?
How do I make a website a trust side in the Safari web browser?
Question about apple ids

We've generally just setup people with their own apple id, but now we are using apple business manager, should I setup these users in apple business manager and give them a new user id? since I cannot re-use their other one? or can apple attach their user id to my business manager account? Do I set them up as staff?

Not sure the best way to manage my organizations apple ids

I have a MacBook Pro (2017) running 10.14.4.

For the first time in a month I shut it down on Friday. I went to start it up on Sunday morning and haven’t been able to boot.

After going through a couple restore attempts, and with the latest one saying it was successful, I am still getting the same results: a Black Screen with a White listing bar and the white “dot circle”. This eventually got to flashing between the black screen and a cursor in the upper left.

Please help me. I have time machine backups as event as Thursday. Any suggestions would be immensely helpful.
I have a Macbook Air mid 2011 (model A1369) and a MacBook Pro 2017.  I would like the MB pro to connect to the old MBA (which has a broken LCD screen so cannot view it properly) and see the display contents.

Can I do this wirelessly.
I have a 2012 MacBook Air which will not power on normally. If the case is removed and the battery is disconnected then it can be powered on when running on AC power. Once successfully powered on, the laptop can be shut down and the battery reconnected, then it will power on from battery power once. The battery holds a charge and seems fine. It discharges at a normal rate and charges normally if connected to AC power. If powered down on battery power, then the laptop will not power on till the battery is disconnected and it is connected to AC power.

Troubleshooting done:
I have reset the SMC (After your Mac shuts down, press Shift-Control-Option on the left side of the built-in keyboard, then press the power button at the same time. Hold these keys and the power button for 10 seconds.) and I've reset the NVRAM (Locate the following keys on the keyboard: Command (⌘), Option, P, and R. Turn on your Mac. Press and hold the Command-Option-P-R keys immediately after you hear the startup sound. Hold these keys until the computer restarts and you hear the startup sound for a second time.)

Has anyone come across this issue and know what the possible cause/fix is? Thanks
There is a need to copy the contents of the desktop contents of MAC to a Synology Server.
All on the same internal network.
When using software such as SyncBack Pro, it produces various errors which prevent some but not all files to be copied.
Access is denied for some files, since they cannot be copied I believe due to permissions.
How can I copy the files without it's permissions,  using either SyncBack Pro or another software program which runs on a Windows computer to backup those desktop MAC files to a Synology share?
Thank you.
Update to Office Mac Mini systems

I am looking for general office update info. I am the only user of these systems

Currently I have 2 Mac mini (late 2012 & late 2014) both running macOS Mojave

Late 2014 has 2 non-4k displays from earlier Windows PCs & 8Gb RAM

Late 2012 has 1 non-4k display  from earlier Windows PC & 8Gb RAM

Each has Acronis backup to local 2TB HD and Apple Time Machine Backup

My computer work is > 95% working with text documents (Pages, Word) and email.
Image work is limited to infrequent iPhone image touchup with Affinity Photo + output to SmugMug.
Swift Publisher is also used to enhance document layout.

My thought is to have 1 Mac Mini with more than 8Gb RAM [16 Gb?) and using all 3 displays for multitasking Pages/Word/etc. documents. I am looking for faster response time to input which is currently *very* slow to activate. System startup time is minutes…

Seems a 2018 Mac Mini has considerably more processing power than I need

I would appreciate Mac Mini model (Year) and Memory (RAM) recommendations.
Hello - I am having trouble syncing my Mac photo albums with my iPhone 8. It was syncing a few weeks ago, but now appears to have stopped syncing updates to my photo albums and photo library from Mac to iPhone. The calendar still syncs, but photos do not. I have no idea why this could be. I have everything turned on (i.e. Photo Stream and iCloud Photos) on both my Mac and iPhone. Both area also completely up to date. The Mac just suddenly stopped syncing my photo album updates with my iPhone. Do you have ANY idea whatsoever why this might be? Help!
I need a GUI client for sftp on MAC.
I have downloaded cyber duck. And i could connect to a sftp machine with port 22.
But then i tried another machine with port 7122. It seems it doesnt have ability to handle this port.
Although i am able to connect if from terminal.
On cyber duck if i manually change the port to 7122 it doesnt work.
It throws the following error :
Please help in suggesting some way to connect to this through some GUI client.
Mac isn't showing other users so another user can't login to the Mac.

The mac was binded to Windows Active Directory to allow users to login with their domain account. We have found that sometimes the option to login with another account just disappears and does not reappear even with a restart to the Mac. The temporary work around I've found is that if I login with the local admin account and just go through the same steps of binding the Mac (Even though it has been binded already) and then just log out the Other User option appears on the login screen.

So my question is there a more permanent fix so this doesn't keep happening?

MacOS 10.14 Mojave
Using Quickbooks for Mac 2016.  When I open one of my company files, the Customer Center window opens, because I had it open when I last closed Quickbooks.  Then I see 3 or 4 other windows open and disappear (a Deposit window, a Timesheet window, I think.)  

When the window-opening animations complete, the one open windows can be dragged into new positions, but not resized, and not closed, and does not recognize any mouse or keyboard interactions.  The program itself displays every menu item as hidden.  I have to Force Quit Quickbooks to take it down.

I tried reinstalling the program, but I get the same behavior.  Odd, because this company file was working fine just two days ago.  I back up every time I close the file, and I've tried restoring some recent backups, but they behave the same, even backups taken from a week ago.    Not sure what to do next.

Time Machine couldn't complete backup to "[Name] Time Machine"

With 2 Macs (Mojave), I am unable to continue Time Machine backups. I have to erase drive to continue.

Seems in the past with earlier OSX versions I could rely on Time Machine to delete older files and continue with backup.

Why not now? Can I automate the erase/restart backup procedures?
