With the release of macOS Big Sur & macOS Monterey, the user cannot format External Hard Disk to ‘Mac OS Extended (Journaled, Encrypted)’ format as there is no option to do the same.
With the release of the macOS Big Sur Mac Operating System, Apple has removed the option under Disk Utility to allow users to format External Hard Drive to Mac OS Extended (Journaled, Encrypted) format.
Now there is only one option for Mac OS Extended (Journaled) but no option with encryption. It only allows users to format Hard Disk with Apple File System APFS without encryption, with encryption & with case sensitivity.
In-depth Review of Matrimony Website by Anuroop Wiwaha (anuroopwiwaha.com)
I am using the Anuroop Wiwaha Matrimony Website for the last four-five years. I have used their mobile Apple iPhone app and website extensively for my bride search all along. There are a few points that I discovered that Anuroop Wiwaha Portal / Company improve upon to help the community get the right matrimony match for their search.
Observations:
Few Points that they can improve on.
Mobile App & Website Portal:
- Every event they always talk about having 20,000 Profiles / Accounts of bride and groom registered on their portal. An average Anuroop Wiwaha account cost is INR 5,000/-.
- User (Bride or Groom) can’t register with a free account as they don’t support free accounts as the user has to pay an account fee upfront before registering to the portal. So it kind of gives assurance that user is at least serious about their search and even user has to submit identity proof within 7 days of registration. So in a way, it eliminates the possibility of fake accounts or frauds.
- Even with this money of 20,000 Accounts * 5,000 Fee, Bride or Groom Search is cumbersome and hectic. The mobile app is not full fledge as compared to a web portal. They are using non-native software technologies for the Apple iPhone app that app takes minutes to load or sometimes fails to load content and data.
Here is how to apply UIVisualEffectView & UIBlurEffect to UITableView, UITableViewCell, UICollectionView, UICollectionViewCell, UIView / View in your Apple iOS / iPadOS or macOS Catalyst App.
As Apple describes UIVisualEffectView & UIBlurView in its support document as follows:
Depending on the desired effect, the effect may affect content layered behind the view or content added to the visual effect view’s contentView. Apply a visual effect view to an existing view and then apply a UIBlurEffect or UIVibrancyEffect object to apply a blur or vibrancy effect to the existing view. After you add the visual effect view to the view hierarchy, add any subviews to the contentView property of the visual effect view. Do not add subviews directly to the visual effect view itself.
So in simple words, you don’t have to use Adobe Photoshop to get blur effect and fake superimpose on your UIView rather you can get the same effect programmatically for every situation without any hassle.
Note: If you are using UIVisualEffectsView in your app I would strongly suggest you use a system setting called ‘Reduced Transparency’ to condition code it. If the user doesn’t want transparency or Blur or Vibrancy effect for all of the apps in his iPhone or iPad or Mac he can just do it with a single switch in the settings app. Another note view that you are applying effect should preferably be the Popover View Controller. Another thing is to remember to replace the below blue color with the UIColor of your choice with alpha channel transparency.
For UITableView and UITableViewCell, use following code in your UITableViewController’s viewWillAppear function:

As Apple describes Pointer Interactions in it’s support document:
Pointer Interactions: Support pointer interactions in your custom controls and views.
iPadOS 13.4 introduces dynamic pointer effects and behaviors that enhance the experience of using an external input device, like a trackpad or mouse, with iPad. As people use an input device, iPadOS automatically adapts the pointer to the current context, providing rich visual feedback and just the right level of precision needed to enhance productivity and simplify common tasks.
Note: UIPointer Interaction is only related to iPad / iPadOS app
Initial Step: Add ‘UIPointerInteractionDelegate’ in your View Controller’s Class Declaration
For UIButton:
Out of Box Implementation:
button.isPointerInteractionEnabled = true
UIView and Custom Implementation for UIButton:
