先日iMac 2011 を Yosemiteにアップデートしました．しばらく使っていて，スリープすると，復帰に失敗することがあることに気づきました．みーが調べた対処法をまとめておきます．
みーの環境 {#みーの環境 style="color:rgb(55, 55, 55); font-style:normal; text-align:start"}
- OS X Yosemite 10.10.1
- iMac (21.5-inch Mid 2011)
- Processor 2.5 GHz Intel Core i5
- Memory 12 GB 1333 MHz DDR3
- Graphics AMD Radeon HD 6750M 512 MB
Yosemiteはリカバリーパーティションからクリーンインストールして使用中．
とりあえずセーフモードで起動 {#とりあえずセーフモードで起動 style="color:rgb(55, 55, 55); font-style:normal; text-align:start"}
Appleのサポートページに，セーフモードで起動する方法が書いてあるので，これにしたがってセーフモードで起動してみました．起動時に音がなったらShiftを押し続けるだけです．しかし，そもそもセーフモード中にスリープしても問題が起きなかったので，OSの中枢でない何かが悪さをしているのかな，ということしかわかりませんでした．
仕方がないので，SMCリセットをしてみる {#仕方がないのでsmcリセットをしてみる style="color:rgb(55, 55, 55); font-style:normal; text-align:start"}
AppleのサポートページにSMCリセットの方法が書いてあるので，これに従ってリセットを行いましたが，やはり問題は解決しませんでした．
クリーンインストールもしたし，起動ディスクの修復はセーフモード起動時に自動実行されるので改めて実行しても意味がないので，もう少し頭を使わないといけないようです．
ログをにらめっこする {#ログをにらめっこする style="color:rgb(55, 55, 55); font-style:normal; text-align:start"}
以下がスリープからの復帰に失敗した時のkernelログです．Utilities/Console.appからコピペ．このログは読み飛ばして次へどうぞ．

ざっと見た感じ以下の部分がヒントになりそうかな．
Failed to get hibernate image filename The USB device Keyboard Hub (Port 2 of Hub at 0xfa100000) may have caused a wake by issuing a remote wakeup (3) Sleep failure code 0x00000002 0x27006700
おそらく，メモリーの内容を一時的にHDDに書きだしたファイル(hibernate image file)に何らかの問題が発生しているのが原因かと思い，ターミナルを開いてpmset -gで確認したところ，(詳細はこちら)
xxxx-iMac:vm xxxx$ pmset -g Active Profiles: AC Power -1* Currently in use: hibernatemode 0 halfdim 1 womp 0 networkoversleep 0 sleep 0 Sleep On Power Button 1 ttyskeepawake 1 hibernatefile /var/vm/sleepimage autorestart 0 disksleep 0 displaysleep 10
となっていて，hibernatemodeは0で，hibernatefileは/var/vm/sleepimageだったので，hibernatemodeを3に，hibernatefileを削除して再起動した．ちなみに/var/vm/sleepimageは/private/var/vm/sleepimageのエイリアスである．
その後スリープから復帰するかを何度か試してみたが，うまく復帰するようになった．現在のところこれで問題がない．
どうしても直らない場合 {#どうしても直らない場合 style="color:rgb(55, 55, 55); font-style:normal; text-align:start"}
以上のことをやっても復帰に失敗するようならば，スリープ機能を使用しないように設定してOSのアップデートで解決されるのを待つ，というのが最善かもしれない．スリープまでの時間をしないにして，スリープボタンを押さないようにするわけである．
後日談 {#後日談 style="text-align: start;"}
Yosemite 10.10.5をクリーンインストールしたら治りました．よかった．(2015.9.24)
