Problems with apps from the Mac App Store?

Recently, Apple sent all developers this email, which contains helpful information in case you suddenly experience problems with applications obtained from the Mac App Store:

As a reminder, the Apple Worldwide Developer Relations Certification Authority Intermediate Certificate expires on February 14, 2016 […].

[…], we want to make you aware of potential issues your users may encounter due to the renewed certificate. Users running OS X El Capitan (v10.11 or v10.11.1) may receive a notification that your Mac app is damaged if it utilizes receipt validation to request a new receipt from Apple. They can resolve this issue by restarting their Mac or updating to OS X El Capitan (v10.11.2). Mac App Store customers running OS X Snow Leopard (v10.6.8) will be unable to purchase new apps or run previously purchased apps that utilize receipt validation until they install the Mac App Store Update for OS X Snow Leopard, which will soon be available via OS X Software Update.

I cannot find the Deck Editor. Where is it?

The latest versions of Wiz Solitaire are available exclusively on the Mac App Store. The Deck Editor is not provided, but you can still download it from this address.

In previous versions, the Deck Editor was shipped together with Wiz Solitaire. When you downloaded and mounted the dmg archive, you would have found these files:

WizSolitaire-*.dmg contents

Typically, you should drag’n’drop the whole WizSolitaire folder into your Applications directory. In this way you’ll also install the Space deck, which you can use as an alternative to the Standard one (other decks are available for download).

Is it possible to play Spider with more than one suit?

Yes: you can use the New Game with Options… item under the Game menu to choose how many decks you wish to play with.

You don’t need to do it every time you start a new game, since it will remember the last used setting.

The same menu item can be used to set the options for other games as well (for instance, in Klondike you can use it to change the number of cards dealt when clicking on the deck or to allow partial column moves).
