How Do I Clear Apple Mail Cache and Temporary Files on Mac?
Are you looking for a simple way to resolve how to clear Apple Mail cache on Mac, and also how to delete temporary file in Mac? Then you must go through this article. Here we will know the best simple solution as possible. Apple Mail for Mac OS is a convenient way to manage email accounts. But over time users experience lots of cached data including temporary attachment files, deleted messages, and other local mail data. When this happens, Mac Mail may consume a considerable amount of storage and can sometimes become slower or behave unexpectedly. In this guide, we will explain how to clear Apple Mail cache and temporary files safely.
Why Should You Clear Apple Mail Cache on Mac?
- Increase storage usage
- Slow Mail performance
- Problems with message searching
- Incorrect or incomplete message displays
- Issues with attachments
- Mail database or indexing problems
Method 1: Go with Finder to Clear Apple Mail Attachments Cache
The most storage space in Apple Mail is taken up by the Mail attachments cache folder, which is also referred to as Mail Downloads. An attachment will be copied to this folder each time you open it.
How to Get Rid of Downloaded Attachments:
Step1: Use $\text{Cmd}+\text{Q}$ or File > Quit Mail from the top menu to end the Apple Mail program entirely.
Step2: Open the Finder.
Step3: Press the Go button at the top of the screen, then click Library while holding down the Option key. (On the Mac, the Library folder is hidden.)
Step4: Go to this folder: Containers/com.apple.mail/Data/Library/Caches/mail
- Locate the “Mail Downloads” or “com.apple.mail caches” folder.
- Drag everything in the “Mail Downloads” folder to the garbage.
Method 2: Delete Unnecessary Emails and Attachments to Clear Apple Mail Cache on Mac
One of the safest ways to reduce Mail’s storage footprint is to remove emails and attachments you no longer need.
Open Apple Mail and review folders such as Inbox, Sent, Junk, and Bin/Trash. Search for large messages and attachments that are no longer required.
After deleting unwanted messages, empty the Bin by selecting Mailbox > Erase Deleted Items.
Note: Simply deleting an email does not necessarily remove it permanently; deleted messages can remain in the Bin until they are erased.
You can also remove attachments from messages when appropriate. Apple notes that removing an attachment from an IMAP message can remove it from the mail server as well, so make sure you have saved anything important before doing this.

Method 3: Clean Temporary Mail Downloads
Apple Mail can temporarily store attachments in the Mail Downloads folder. Apple’s Mail settings include a Remove unedited downloads option that controls when attachments temporarily saved in this folder are removed. To review this setting:
- Open Mail on your Mac.
- Select Mail > Settings.
- Open the General section.
- Look for Remove unedited downloads.
- Select the appropriate cleanup option.
This is preferable to randomly deleting files from the Library because Mail provides a controlled way to manage temporary downloads.
If you want to inspect the Mail Downloads location manually, it is located within your user Library. In Finder, choose Go > Go to Folder and enter:
~/Library/Mail/
Method 4: Rebuild an Apple Mail Mailbox
Sometimes what appears to be a cache problem is actually an indexing or mailbox database issue. For example, messages may not appear correctly in search results or some messages may seem missing.
Apple Mail includes a Rebuild function for this situation. To rebuild a mailbox:
- Open Apple Mail.
- Select the affected mailbox from the sidebar.
- Click Mailbox in the menu bar.
- Select Rebuild.
Apple specifically recommends rebuilding a mailbox when messages appear missing or garbled, or when Mail search isn’t finding messages correctly.
The rebuilding process may temporarily change how much storage Mail uses because the application may need to recreate local mailbox information.
How an Automated Migration Tool for Apple Mail Converter Can Help?
CubexSoft Apple Mail Converter is a beneficial solution, when you need to preserve your emails before cleaning, changing email clients, or migrating data to another platform. Instead of converting a single file at a time, the tool can help export Apple Mail data into a format supported by another email application or storage system.
For example, if your Mac contains years of old Apple Mail messages that you rarely access, you could first export or convert those emails for long-term archival. You can then remove unnecessary local copies from Mail and potentially recover storage space.
Wrap Up
Resolving how to clear Apple Mail cache on Mac, and also how to delete temporary file in Mac reduce unnecessary storage usage and may resolve certain Mail performance or indexing problems. The safest approach is to begin with built-in Mail features rather than deleting the entire Mail Library manually. First, back up Apple Mail. Next, remove unwanted emails and attachments, empty deleted items, review temporary download settings, and rebuild mailboxes when search or message display problems occur. If you have a large collection of important emails and want to clean up your Mac without losing access to them, the suggested software can provide an additional option for exporting or archiving messages before cleanup.
