Sometimes a download is incomplete because the file was damaged. Try downloading it again. Make sure you have the app needed to open the file. If you do, the file may have been corrupted during the download. Delete it, then try downloading it again. The downloaded file may be a compressed archive or disk image that contains the file you want. If you can’t open Mail on your Mac. If you try to open a version of the Mail app that can’t be used on your Mac, an alert message is displayed. Make sure the version of Mail you’re trying to open is located in the Applications folder.

1. Unable To Download A File From My Email On Macbook Air Louder

Hi I was wondering if anyone can help me with an issue I currently have with my mac book air?

MacBook Air info:

-Purchased new, late 2012

-Processor: 1.7 GHz Intel Core i5

-Memory: 8 GB 1600 MHz DDR3

-Storage Capacity: 120 GB

-Storage Capacity Free/Left: 68 GB

-Current OS X 10.9.5 (13F1911)

I am trying to download 'Microsoft One Note' onto my MacBook Air but it won't seem to let me. It keeps coming up with an error message;

'We could not complete your purchase. (null) can’t be installed on “Macintosh HD” because OS X version 10.10 or later is required.'

I have however downloaded and installed the 'macOS High Sierra' recently.

This problem occurs to other apps as well when i try to download them off the App Store onto the MacBook Air.

Any help/advice on what to do?

Add an email account

If you haven't already set up an email account in Mail, you might be prompted to add one when you open the app. If you're not prompted, or you just want to add another account, follow these steps:

1. From the menu bar in Mail, choose Mail > Add Account.
2. Select your email provider from the list, then click Continue.
3. Some accounts, such as Google, might ask that you click Open Browser to complete authentication in your web browser.
4. Follow the onscreen instructions to enter account details, such as your name, email address, and password. If you're not sure what information to enter, please contact your email provider for help.

Use the Inbox for each account

The Inbox gathers together the messages for every email account you added. If you added more than one account, you can click the disclosure triangle next to Inbox in the sidebar, then select a mailbox to see only the messages for that account.

Optional: Turn on other account features

If your account includes support for contacts, calendars, notes, or other features in addition to email, you can turn those features on or off:
