Here are a few tricks worth trying.<\/p><h3 class=\"wp-block-heading\" id=\"h-make-a-backup\">Make a Backup<\/h3><p>Before repairing a corrupted DMG file, make sure you have a backup. While there is a chance that the disk will be repaired, it is equally likely that it will be damaged even more if you try.

After that, it is hard to restore them. The only way is to use the professional restoring application to get your files back.&nbsp;<\/p><ol start=\"3\" class=\"wp-block-list\">\n<li>Before you delete any of your files, double-check and make sure you do not remove any important data.<\/li>\n<\/ol><h2 class=\"wp-block-heading\" id=\"wrapping-up\">Wrapping Up<\/h2><p>DMG files are great for installing apps on a Mac. Encryption and compression features make it much more secure than other file formats. However, it can also be a hassle when macOS doesn&rsquo;t recognize the file because you can&rsquo;t open it or access the content. If it happens, don&rsquo;t worry, as you can still try to fix and restore your DMG file successfully.<\/p><h2 class=\"wp-block-heading\" id=\"faqs\">FAQs<\/h2><p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The data on your Mac should be treated carefully and responsibly.
