My Macbook Air had similar problems loading images on certain websites like CNN and CNBC. Text would load with blank areas left for the missing images until they finally loaded as much as a minute later. I tried all of the techniques on this and other sites including loading a new copy of El Capitan (I did not wipe the drive first) with no success.
Use the steps in this article if this happens in Safari on your Mac:
- You can’t log in to a secure website.
- A webpage repeatedly reloads or redirects.
- A message on a webpage tells you to remove or reset cookies.
- Some images, videos, or other items aren't displayed on a webpage, but other page elements load.
Check Parental Controls
If you're logged into a user account that is restricted by Parental Controls or other web filtering software, some pages or page elements might not load if those sites aren't allowed. For example, embedded videos might not display if they're hosted on a site other than the one you're viewing.
Check with your administrator to see if you can get access to the site that you're trying to view.
Check Safari extensions
Some Safari extensions that block ads or other website content can prevent some page elements from displaying. You can temporarily turn off extensions, then re-load the page to see if this is the issue.
- Choose Safari > Preferences.
- Click Extensions.
- Select an extension, then deselect the checkbox 'Enable… extension.' Repeat this step for every extension that's currently installed.
Reload the page by choosing Choose View > Reload in Safari. If the webpage loads correctly, one or more extensions was blocking the content from loading. Re-enable an extension, then reload the page again to determine which extension is blocking the content you want to view.
If the website still doesn't load with all of your extensions disabled, try the next steps in this article.
If Safari doesn't load pages from a specific site
If only one webpage or website isn't working, you can remove data related to that site to see if it fixes the issue. Use these steps to remove cookies, cache, and other data stored by Safari for a specific site:
- Choose Safari > Preferences.
- Click the Privacy icon.
- Click the Details button.
- Search for the name or domain of the website whose data you want to remove.
- In the results list, click the domain (like example.com) that has data you want to remove.
- Click Remove.
- When you're finished, click Done and close the preferences window.
If you used the Private Browsing feature of Safari when visiting a website, you might not see the site listed here.
If Safari doesn't load pages from multiple sites
In OS X Yosemite, you can delete website data for the past hour, or past few days if websites or pages stopped loading recently.
- Choose History > Clear History and Website Data.
- In the sheet that appears, choose the range of data you want to remove from the Clear pop-up menu.
- Click Clear History.
If you want to remove website data for all of the sites and pages you've ever visited, choose 'all history' from the Clear pop-up menu. The option to Remove All Website Data in the Privacy pane of Safari preferences does this, too. These options also reset your browsing history and Top Sites.

To learn more about cache, cookies, and other website data, open Safari and search for the word 'history' or 'privacy' from the Help menu.
I'm a very experienced Mac tech support consultant, yet I've been grappling with the 'too many corpses' problem since yesterday. I tried a number of approaches, but was confident that a simple solution existed. YOU MAY NOT HAVE TO ERASE YOUR HARD DRIVE, or reinstall Mac OS. I found a couple of postings that explain this surprisingly quick solution. If you're able to get into Recovery Mode utilizing CMD-R, and you're not afraid to work in the Terminal program, THIS WORKS! If you follow these steps EXACTLY, a bad file named 'mbr_cache' will be rebuilt and your Mac will reboot successfully (slowly the first time as the rebuild happens, then normal speed after that). This solution worked on my 2011-vintage 21-inch iMac (iMac 12,1) with Mac OS High Sierra. Someone should tell the Apple Geniuses and Tech Support Specialists about this. Or, better yet, they should be able to find these types of solutions themselves. Good luck!
