As per my screenshot (attached), one of my Gmail accounts keeps show as 4 unread messages for about 5 seconds, and then it changes back to 0... or if I actually have 2 unread messages, it will show as 6, etc... then back to the 2 (the real unread number).

- it doesn't happen any of my other Gmail accounts
- it only happens on my iPhone and not on Mac Mail or Gmail in web view
- i've deleted the Mail account and re-added it... but the problem still persists
- i went into the account on my iPhone and selected all emails... marked them all as unread... then selected all again and marked them as read... but the problem still persists

Any help at all would be much appreciated.

When user does a screenshot, there is a delay before it appears on the desktop, it normally appears once he has deleted something else.  
Also, if user drags a file from an email or somewhere else on to the desktop or in to a folder, it again does not appear straight away, but will after some other form of action is taken.

This has been observed on couple of Macs: 10.10.5 and 10.9.5.
We have older Macs that do not have this problem.

Do you have any idea what may be going on there?
I really know very little about Macs.

A friend sent me this about his macBook laptop

I was updating my hard drive with my external hard drive this morning and the computer froze midway through. I turned the computer off and unplugged the external hard drive which may have been my first mistake. The entire hard drive seems to be deleted and I have no operating system. The computer starts up and goes to a list of OSX reinstallation options. At this point I don’t want screw anything else up. I last backed up in mid April so I won’t lose that much considering I send most files out by email.  Can you help get me going?

Anyone know where to start with this? He was using time machine - is that an  image of the hard drive / we restore the image and we're done?  Or is it just backup of certain files / folders? We'd have to install the OS, apps, configuration, .etc?  HGe talked of removing the external hard drive... not sure if he corrupted that too?

Would anyone care to share some advice where to start to get that machine going again?

The machine is only a couple years old.

Somehow, I have a 'mac os and install disk 1' for 10.5.4.  taht's copyright date of 2008.  (NOT from his machine, just a disk I have on my shelf.

And I have a bunch of USB disks if there's a place / need to download the OS.

But I have no clue where to start.

Connecting a Mac to a Large flat screen TV?

I use High Sierra and hope to make a presentation using a Large flat screen TV in a rented conference room.

Then what?


I have a user who is using an iPhone X and is trying to connect to exchange via the apple mail app but keeps getting the error message "Cannot get mail the connection to the server failed."

In the Exchange Admin Center for Exchange 2013 I only see a total of 3 devices under mobile devices, the users iPhone X, My phone and an iPad that is working fine, so I know I am below the ten device max connection.

What is the Max folder size on a Mac High Sierra?

I have about 580 MB of images in the same folder, and noticed when I scroll through them in Finder, I sometimes see the selected image file skip over to the bottom file in the folder.

It really throws me when I am looking for a certain file.

Is this too much capacity for a single folder?

Or, might there be a bad file causing some other type of error?

Hi, I am a member of a website that has a number of AVI videos. I only use IPad Pro and do not own a pc/laptop.

Appreciate any assistance.
Getting iMessage working on my Mac

I use iMessage for many months and loved that I could read and send text messages on my Mac. But I upgraded my iPhone 6 to an iPhone 7 and found iMessage spotty.

I need to re-initialize iMessage so that all my text messages can be read and updated on my Mac.

How do I do this?

Do macOS come with any full disc encryption and option for encrypting inserted USB before they can be written too, similar in fashion to bitlocker and bitlocker to go on later releases of windows OS. If they do can you provide details, and any tips on how you could verify that these encryption controls (FDE and USB) have been applied to all devices in the environment? we need some assurances from a partner for security audit and are aware they run macos.

out of interest are there any major providers of anti virus for macOS or does the OS itself have any inbuilt AV similar to windows defender?
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?

I have been granted full access to two Office 365 Shared email boxes.

These two email boxes both appear in the left-hand column of my Outlook 2016 for Office 365 on my Windows 10 computer.

However, these two email boxes don't appear anywhere within Mac Outlook 2016 for Office 365 on my Mac OS X computer which is running macOS High Sierra Version 10.13.4.

What do I need to do to add these two shared email boxes so that they will appear within my Mac Outlook 2016 for Office 365 on my Mac OS X computer?

All Office and Mac updates have been installed on the Mac computer. Mac Outlook is running version 16.12 (180410).

Why is my Time Machine disk empty?

I re-formatted the disk and added encryption. Time Machine backed it up and it worked fine. But when I view the disk in Finder, it's empty.

Conversely, Get Info shows there is data on the disk.

Empty Drive
I feel like the old unencrypted Time Machine partition is still accepting new back-ups. And the data is NOT-encrypted.

I need to start fresh and wipe out all partitions on the disk, then have Time Machine function.

What am I missing?

Dear experts,

In my city in India I have the LenovoYoga520Q6IN, 7i3/4/1/FHD/MS14/W10 laptop.

Now i am trying to compare the features/strengths and limitations of the above laptop with Ipadpro 12.9inch.

My  primary focus of this new purchase is purely note taking/saving/extracting parts of pdf document and copying it on word (or equivalent) and saving the files on the hard disk.

Kindly let me know your views/experiences.
How do I stop the iPhone 7 from requiring a log in!

I go out and take pictures and I swear every tie I put my phone in my pocket, I need to enter the password.

I need it to stop harassing me and destroying my productivity.

I never leave my phone in places where it could be compromised anyways...

Adding a password to an external disk?

I just cleaned of the entire disk and used TimeMachine to save to the disk. But I realized I need it password protected.

How do I add that?
